Please check your nodebb logs for any errors.

thank you @baris

i runned ./nodebb log and there is no error in the log.

runned ./nodebb dev and result is ;

That's not the error @baris needs. That's related to your NodeBB already running and you attempting to run it again.

Please stop NodeBB completely and start again, and try logging in with a non-existant user, and then check the logs via (./nodebb log)

i tried everyting, reinstalled nodebb. but i get same error. Any idea please.

thanks

julian

Those logs do not show a NodeBB crash, unfortunately, so we cannot help you yet.

today nodebb stopped suddenly and my site turn 502. after i start nodebb again the error has disappeared. how can i learn why nodebb stopped. there is no data in log.

note; error came back after 1 hour.

atozsoft

i tried more times, i installed nodebb more times ( with redis). same issue. when i try to login with non exist user nodebb stops ( to test when i try 5 times to login with non exist user nodebb stops) . and i get Internal Error. Oops! Looks like something went wrong! error. i read all instrunctions but no success. *server is ubuntu 16.04 on aws ec2 *

atozsoft

finally fixed.

i think it was an issue about redis. i reinstalled nodebb with mongo and there is no error.

notes;

when i was trying to login with non-exist user with nodebb/redis it was giving errors and error message was only Login Unsuccessful and nodebb was stopping after 5 attemps.

and now if i try to login with non-exist user with nodebb/mongo error message is Login Unsuccessful
invalid-login-credentials
and nodebb does not stop.

the only thing i am wondering now is ./nodebb dev results.

they are;

Looks like a bug on that only happens when using redis, thanks for reporting.
