I’m not sure if this is a Yunohost SSL cert thing, or a DavX5 thing, but I searched for similar issues here and didn’t quite find anything that matched. Basically, I have Nextcloud setup with a Let’s Encrypt cert. I don’t get any errors on visiting the site through a web browser, or when using the Nextcloud app.
DavX5 though keeps asking me to inspect the unknown certificate. Given that it’s issued by a known certificate authority, I’m wondering if there’s something set up wrong? (Especially since the domain is listed as [2]MyDomainName instead of just MyDomainName).
Sorry, I did check diagnostics but forgot to add it here. Anyway, no, there are no related issues showing in diagnostics. The only issues are things like showing the metronome and yunohost-api services not running (which I turned off on purpose).
You may be onto something with the IPV6 thing though. I remember when I was troubleshooting Matrix/Synapse that it was saying that everything but IPV6 was working, which didn’t bother me as I only (knowingly) connect via IPv4.
TBH while I have plenty of experience setting up websites and services with IPv4, I’ve never gone down the IPv6 rabbit hole. How would I go about testing this theory? I don’t need a detailed step by step, just an idea of what to search for online.
