I used to login into Gluu Server CE by calling my url ``` https://gluub18.fritz.box/ ``` Gluu redirects to the login box at ``` https://gluub18.fritz.box/identity/login.htm ``` Now i am only getting a ``` 502. That's an error. The server encountered a temporary error and could not complete your request. Please try later again. ``` Reloading the page next day had the same behaviour. So i looked into the oxauth.log (i never looked there before) after booting the gluu server: [oxauth.log](https://pastebin.com/1V2u9LfW "oxauth.log") ``` Line 21.-24. : Scheduler class: 'org.quartz.core.QuartzScheduler' - running locally. NOT STARTED. Currently in standby mode. Number of jobs executed: 0 ``` astonishes me. ``` curl -kLv https://gluub18.fritz.box/oxauth ``` gives back this: [curl.oxauth](https://pastebin.com/reDbrQEA "curl.oxauth") Is there a chance to fix that temporary error and get back a login box? Regards, Johann

Did you restart the server? Also, ssh to the box and check the disk space : ``` # df - h ``` Make sure opendj is starting ok and running. ``` # ps -ef | grep java ``` Also see if the oxauth or oxtrust logs give you any hint.

Yes, Server is restarted. Disk space is fine: ``` # df -h Filesystem Size Used Avail Use% Mounted on /dev/vda1 54G 16G 36G 30% / -- snip -- ``` opendj started ok: ``` # service opendj status ● opendj.service - OpenDJ Directory Service -- snip -- Active: active (running) since Sat 2022-06-18 03:15:48 CEST; 39min ago -- snip -- ``` The complete opendj status is here: [opendj.status](https://pastebin.com/Gf5VW8et "opendj.status") oxauth.log is silent. ##### oxtrust.log shows an error: ``` 2022-06-18 01:31:14,749 ERROR [Thread-160] [org.gluu.oxtrust.service.StatusCheckerTimer] (StatusCheckerTimer.java:183) - Can not download ssl certificate java.net.ConnectException: Connection timed out (Connection timed out) ``` The complete oxtrust.log is here: [oxtrust.log]( "oxtrust.log") During Server-Setup i just generated the Gluu Server Certificate which can be accessed from outside: ``` $ openssl s_client -connect gluub18.fritz.box:https CONNECTED(00000003) depth=0 C = DE, ST = BY, L = Muenchen, O = Hoermann Solutions, CN = gluub18.fritz.box, emailAddress = trash@discard.email -- snip -- ``` Which certificate is oxtrust trying to download?

Hi Johan, **Which certificate you have generated manually during setup?** > During Server-Setup i just generated the Gluu Server Certificate which can be accessed from outside It's not require to generate manual certificate during installation.

You are right Mobarak: It was not me but the ./setup.py which generated the server certificate. I just gave the hostname and other stuff when i was asked for by ./setup.py. Anyway, i could login into the Gluu Server ``` https://gluub18.fritz.box ``` for a couple of days, until that error 502 was coming up. Do you think an upgrade to Gluu Server 4.4 might fix the problem? Regards, Johann

I'm not sure that upgrading will fix the problem. It's better to fix the problem first, then upgrade the latest one. Can you please check the status of `identity` and `oxauth`? ``` systemctl status identity systemctl status oxauth ```

Status log of both services: [identity-oxauth.status](https://pastebin.com/zEy3B6mk "identity-oxauth.status") Do you like to see the jetty.log file?

Thanks for the resources. I see both of them are running. That error might be because of server overload or network issue. - How many services are running? - What is the memory size of VM? - Kindly check that [VM Requirements](https://gluu.org/docs/gluu-server/4.4/installation-guide/#system-requirements) was fulfilled. Regards ~ Shakil
