Nextcloud version (eg, 12.0.2): 14.04
Operating system and version (eg, Ubuntu 17.04): Ubuntu Server 16.04.5 LTS
Apache or nginx version (eg, Apache 2.4.25): 2.4.18
PHP version (eg, 7.1):PHP 7.0.32-0ubuntu0.16.04.1 (cli) ( NTS )

The issue you are facing:I am running Nextcloud as a virtual Linux server on a Window 2016 Hyper-V platform along with two additional Nextcloud servers. When accessing the Nextcloud logs on this particular server I see that there is a constant stream of user exception logs every 30 secs.
Apart from this annoying issue the server is working fine with 30+ users
I cannot identify the issue and would like to request help from anyone who can shed some light on the possible cause of the problem.

Is this the first time you’ve seen this error? (Y/N): No, it was occurring under Nextcloud 13 and I had hoped the upgrade to 14 would resolve the problem but sadly not

Steps to replicate it:

  1. Access web interface
  2. View logs via Administration/Logging page

The output of your Nextcloud log in Admin > Logging:

Hi Community,
Am I the only one to experience this issue? It must be a rare event but unless I have some major configuration issue, I am suprised no one has comments thus far.

Any advice gratefully recieved, thank you

remoteAddr":“90.243.33.75”
“Exception”:“OC\User\LoginException”,“Message”:“User disabled”,
“absoluteUrl”:“https://my.server.address/nextcloud/remote.php/webdav/

Well, looking at the error message, of course no one else is seeing this.
Obviously webdav probably by smartphone or desktop app (synching of files/ contacts/ calendar). IP to help you find the device. And the reason for that error: the device is configured to login with a user account which has been disabled already.
So what else do you need there? :sweat_smile:

Hi Schmu,

Thanks for your response. I will have a look at the address and see if I can track it down.
I really appreciate your response but please don’t use words like ‘obviously’ and ‘of course’ as I can assure you very little of trying to interpret linux logs is obvious to a non professional IT man like me.
Everyday is a learning curve for me! Thanks again
