Running two nextclouds on Unraid - > occasional 502 error

[MarekNosek]

Hi guys, 

 

I have two nextcloud dockers setup and it all seems to run fine, but once a day the NEXTCLOUD #2 gets the 502 error. 

 

I have the following unraid docker running:

- NginxProxyManager  `autostart wait 0` 
- mariadb  `autostart wait 5` on port 3306
- mariadb2 `autostart wait 20` on port 3307
- nextcloud  `autostart wait 20` on port 444
- nextcloud2  `autostart wait 20` on port 448

 

 

All on bridged network. 
Each nextcloud is directed to via a proxy from Nginx.
Each nextcloud is linked to mariaDB via separate port.

Most of the time all is running fine, but from time to time I encounter the

502 bad gateway when trying to reach the NEXTCLOUD #2

Maybe once a day...

 

 

Steps to replicate it:

1. I assumed that it was a problem of dockers starting too fast.
2. I tried to have a wait time before they start. But problem appears again. 
3. When I **stop** mariaDB2 and and NEXTCLOUD2 and restart it after few seconds, it works again. 

Could anyone suggest where to look for problems?

----------------

 

Nextcloud version: `Nextcloud 22.1.1`
Operating system and version : `UNRAID Version: 6.9.2 `
Nginx version:  `v2.9.9 © 2021`

The output of your Nextcloud log in **Admin > Logging**:
This is the only error warning I get since it has worked:

Just curious, why 2 DB servers?

Best bet is to post in the existing docker support thread:

Different branding and different users.

You could just create a separate DB and save come complexity. If it's all running on the same hardware, there's no performance gain to have 2 docker instances running, just my opinion
