6.9.0-rc2 / Nextcloud VM doesn't start anymore / 502 Bad Gateway openresty failure

Recommended Posts

Hi at all


Since I restarted the nextcloud VM, there is just the following in my browser:

502 Bad Gateway openresty failure


I can't ping the IP of the instance. If I look inside the VM with VNC there is no network configuration available.


At first i thought it has to be a problem with nextcloud. However, it must be due to unraid cause I tried to start the vm from a backup disk.img, but there is the same problem. That's why I think it is aproblem with unraid not with nextcloud.


When I look at the log there is the following. I think the last 3 lines are not ok. But what can I do? I have also the diagnostic file attached.


Would be very nice if someone can help me. This instance runs since 8 months without any problem. Now I can't work anymore...


thank you in advance

Hi there


I realised that if I change in the VM configuration the machine from Q35-5.1 to Q35-4.0 the VM starts normal. But why did it work before? I did nothing change at all.

And what is the difference between the two machines?


Would be nice if someone give me advice to that.


thank you. Greg
