A couple of days I found out, that my NC25, which I believed runs perfectly well, is not reachable on some devices. Of course not on mine, otherwise I would have realized the malfunction earlier.
The instance runs on Ubuntu 22.04 and all I recently did was to renew the certificate and update to 25.0.3. The installation about 6 months ago followed exctly this guide.
I had a look at the error.log and it came up with this.
2023/01/24 04:48:58 [crit] 1000#1000: *26670 SSL_do_handshake() failed (SSL: error:0A00006C:SSL routines::bad key share) while SSL handshaking, client: 184.108.40.206, server: 0.0.0.0:443 2023/01/24 04:55:55 [error] 1000#1000: *26732 access forbidden by rule, client: 220.127.116.11, server: nextcloud.examp.com, request: "GET /.git/config HTTP/1.1", host: "my.external.ip"
I’m not sure, if this is responsible for the malfunction and what this means exactly (I’m not a Nextcloud expert). But obviously there’s an issue regarding the certificate. But why does it work on my PC/Phone and not on some others?
Maybe someone has an idea?
