<![CDATA[UBsync cannot add NextCloud account]]>OTA-15 on OPO

I have my own NextCloud server running on a raspberry pi 3. I used mkcert to generate my own rootCA and SSL certs for the NextCloudPi server. I have installed the root certificate on my Linux-Mint laptop and on the Ubuntu Touch OPO. I can connect to and log into the NextCloud by simply going to https://<MyNextCloudIP> in a browser on my laptop and OPO with no security warnings. But, when I try to set up a NextCloud connection in Calendar on OPO or try to set up a NextCloud account in UBsync using https://<MyNextCloudIP> and my NextCloud credentials I get "Invalid Host URL".

Anyone have any ideas I can try?

I set it up initially without certs and just ignored the security warnings. But then, when I tried to set up an internet calendar in Calendar and it came back with "Invalid Host URL" I thought it might be because the server was not trusted so that's why I went to the trouble of adding the SSL cert on the server and making my own rootCA. But, that did not resolve the issue so I'm back to square one.

Certs without real DNS are always a bit hackish IMHO.

I just wanted to do some testing with UT to see if I can de-Google my life. I don't even have a SIM card in the phone right now so everything is just via wifi. The thing is: the browser on the phone can access the NextCloud server just fine without any security complaints so I think my SSL certs are all in order.

Could it be a DNS thing? Does the Calendar and UBsync check for a valid DNS entry on an external site?

Invalid host URL no matter what URL is given. Calendar synchronization works fine with other, non-UT clients.

Normally I would configure it as a regular web-server and then configure the router to do NAT reflection so that it can be equally accessed from inside the same network.

I have no idea what might be going wrong with your rather uncommon setup though.
