I am currently getting signed out every minute from lemmy.world. This is not a client side cache issue. I tested making API calls from the command line (with curl) with no cache and the issue still occurs. One call I get the correct response, the next I get a 400 telling me im not signed in.

I'm primarily testing with the https://lemmy.world/api/v3/user/unread_count api endpoint. I'm not sure if this issue occurs with all endpoints.

Reproduction steps:

  1. Get a lemmy.world JWT token for your account using your desired method (eg. postman).
  2. curl https://lemmy.world/api/v3/user/unread_count?auth={JWT_TOKEN_HERE}
  3. Note the 400 error. If you do not get an error repeat step 2.

Edit

This issue only seems to affect lemmy.world so a temporary workaround is to use a different instance for the time being.

Just a quick statement from the admins team to say that we are aware of the issue and yes we are looking into this.

Thank you @[email protected] for the elaborate report and everyone else for their patience while we try to sort this one out!

Edit: Lemmy was upgraded to 0.18.2

Thank you for all that you do for this place. I am consistently amazed at how quickly y'all are able to resolve issues.

[–] [email protected] 7 points 1 year ago

Thank you for making a statement about it!

[–] [email protected] 32 points 1 year ago (1 children)

Sounds like lemmy.world runs on 2 instances and the requests are being loadbalanced between those two. That and that the jwt secret is different between those two instances causing one to accept and the other to reject

[–] [email protected] 17 points 1 year ago (1 children)

This is also my theory. I think you’re right on the money here. They probably rotated secrets from yesterday’s hack and forgot to restart both servers.

[–] [email protected] 4 points 1 year ago (1 children)

Does anyone know who can contact the server admins?

[–] [email protected] 7 points 1 year ago (1 children)

Yell real loud in all caps

Same problem for me it seems, dunno if I'll even be able to comment. Refuses to stay logged in.

[–] [email protected] 11 points 1 year ago* (last edited 1 year ago) (3 children)

From my tests, it's almost perfectly a 50/50 whether any API requests you make will yield a 200 (success) or a 400 (not signed in). If you perform an action that takes 3 API requests, your chances of succeeding is (1/2)^3 or 1/8 because only 1 request needs to fail in the chain for the entire action to fail. So, as long as you make single API actions you can maximize your success rate :D

[–] [email protected] 5 points 1 year ago

Seems like spamming actions also gets it to work eventually. It's a pain in the arse though lol. I made some alt accounts on other instances, but I'm lazy and don't wanna rebuild my subscription feed if I don't have to, so hopefully it gets fixed at some point.

[–] [email protected] 5 points 1 year ago (1 children)

What's an example of something that would take more than one API request?

[–] [email protected] 4 points 1 year ago

Signing in. Most websites/apps will probably also grab your unread count, and maybe even your subscription feeds.

Another example is checking your inbox. Lemmy actually has 3 inboxes: mentions, replies and PMs. A lot of websites/apps bundle these three so they will need to check all 3 inboxes via 3 API calls.

[–] [email protected] 5 points 1 year ago

Smells like two instances behind the load balancer, one is fine with the JWT, one is not.

[–] [email protected] 14 points 1 year ago

Thaaats what's going on

[–] [email protected] 10 points 1 year ago (2 children)

Yeah. Lemmy.world is currently unusable on the desktop. I don't have that problem in Memmy. Growing pains but I hope the problem will be fixed soon. Do anyone know if one of the mods in North America are aware of the problem?

[–] [email protected] 4 points 1 year ago (2 children)

I was having trouble in liftoff and the browser. Cleared data and cache from liftoff thinking maybe something got messed up there and now I can't even log back into my .world account πŸ€·β€β™‚οΈ I'll hang here for a bit I guess.

[–] [email protected] 3 points 1 year ago

Same here, can't log in again via Liftoff.

Same issue here, I'm being automatically logged out of my lemmy.world account in Firefox. If I refresh the page even immediately after logging in, I'm automatically logged out.

[–] [email protected] 9 points 1 year ago (1 children)

I’m having to reauthenticate in safari and wefwef every time I load a new page. Furthermore, the login is frequently failing.

[–] [email protected] 11 points 1 year ago* (last edited 1 year ago) (1 children)

Login in likely always succeeding. The issue is that whatever app/website you use will make additional API calls afterwards (eg. fetch posts or fetch unread count). Each of those calls have a 1-in-2 chance to succeed and if any of them fail, they all fail and you will be booted out.

Lemmy is now an RNG game. We must prayge to rngesus before making any actions.

Okay, so how do we get this fixed? Any way to get admin attention? I think @[email protected] is probably correct about the cause.

[–] [email protected] 7 points 1 year ago

FWIW, I can confirm I'm having this issue as well. The load balancing hypothesis seems sound given the behavior I'm seeing. Definitely making lemmy.world pretty much unusable at this point.

[–] [email protected] 6 points 1 year ago

I've been experiencing something similar/related. If I am logged in and open something in a new browser window, it frequently (starting today) shows me as not logged in. If I refresh the page, I'm suddenly logged in. This doesn't feel like a authentication problem as much as a timing issue while loading the page. Or maybe what I'm seeing is an entirely different issue.

[–] [email protected] 5 points 1 year ago

Same here, I thought I was going crazy

[–] [email protected] 5 points 1 year ago

At least when you can't log in on one instance you can just login on another. Downtime doesn't mean you have to go do something else anymore!

I'm seeing the same issues on my app, calling login, then immediately using that jwt to fetch the site details and it doesn't give my_user half of the time, and if my app loads far enough to check the unread count I get not_logged_in

[–] [email protected] 5 points 1 year ago (1 children)

Same here, it’s driving me mad. Also did the above and glad to see I’m not alone!

[–] [email protected] 2 points 1 year ago (1 children)

The good news is it only appears to affect lemmy.world. If you have an account on another instance, you should switch to that account for now.

[–] [email protected] 2 points 1 year ago

I might do that at this point, with the attention world is getting, it might be smart to have a backup.

[–] [email protected] 5 points 1 year ago

Yes I have the issue on Liftoff - can't even log in again. Alt time for now!

[–] [email protected] 5 points 1 year ago* (last edited 1 year ago) (1 children)

I can't seem to comment on a couple specific posts on the instance. But as you can see, it works on this one. I am wondering if that's related? I'm not even on my Lemmy.World account and get an unable to post error as soon as I hit the button, like it's not even trying to do anything.

[–] [email protected] 4 points 1 year ago

From my experience it's entirely random. You can make 5 actions and all 5 will work. Then have a string of 5 actions where none would work.

[–] [email protected] 4 points 1 year ago

This is happening in the connect app and I thought I was going crazy.

[–] [email protected] 4 points 1 year ago

Yeah, was wondering what was going on. Hope it gets fixed soon!

[–] [email protected] 4 points 1 year ago

Just add me to the list. Jerboa seems to stay logged in for about 75% of interactions.

[–] [email protected] 4 points 1 year ago

Making a new post is a nightmare. I wish the submit button would time out in these instances so you can try again. Right now I'm having to copy and paste into a new tab and hope for the best (but fail, 5 times and counting).

[–] [email protected] 4 points 1 year ago

I'm getting this too, even after clearing cookies and logging in again. I've seen it on multiple devices (Android phone, Linux desktop with Chrome).

[–] [email protected] 3 points 1 year ago (1 children)

Lucky I have a .ml account

[–] [email protected] 4 points 1 year ago (4 children)

is there a way to see lemmy instances sorted by subscriber amount ? I might wanna join the smaller ones lol

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago)

Lemmy.Fmhy.ml is a sweet spot. It's in the top 10, but further down the list. Active and ran by cool admins. No issues from massive user counts (so far). The community is pretty strong and active so i imagine it's got some staying power.

It letβ€˜s you sort for all kind of things in regards of instances and communities.

I'm having the same issue... might switch to an alt or something for now.

[–] [email protected] 2 points 1 year ago (2 children)

Same here. All Edge, Firefox and Safari keep logging me off. Same with Memmy iOS app.

[–] [email protected] 2 points 1 year ago (1 children)

The issue is server sided so it will not matter what you use unfortunately. Technically a temp but terrible fix is to keep retrying on 400s (not signed in) until a 200 (success) is returned. This is terrible because you pretty much never want to retry for 400 errors because 400 errors are client side errors (except in this case).

[–] [email protected] 3 points 1 year ago

Thx for elaborating. Not the answer one wants to hear, but at least I won't continue foolishly to restart browser and clear cache / cookies.
