Dashboard and then 504 Gateway Time-Out

IwanSkivol · December 30, 2020, 12:41pm

Hello everyone,

I’ve been running Netxcloud on a docker platform for few weeks or months.
Currently, It is not running properly. The issue is always the same.
Using the URL https://nextcloud.mydomain.tld redirects me to the dashboard page. And then, whatever the link I click, I get an 504 Gateway Time-out error.

The details:

I’m not able to figure out what is wrong, and why I get this 504 error.
Should I increase my logs’ verbosity ?

Any help appreciated.

I connected to my nextcloud container, and played with a few occ command.
I’ve not seen any errors so far, but occ is extremely slow…
