Hey everyone, so I just set up my new unraid-Server and bought a fresh domain "example.de". I set up a swag proxy for beeing able to access my vaultwarden over https and modified the built in vaultwarden.conf file to point to vw.example.de. I also installed a fresh vaultwarden where I set the Domain URL to "https://vw.example.de". The domain was registered on cloudflare to take advantage of the integrated dns valuation of swag and I added a subdomain "vw.example.de" as CNAME. When trying to access vw.example.de the site isn't loading with the error message "SSL_ERROR_RX_RECORD_TOO_LONG" when using Firefox. In front of the unraid server there is a Sophos active where I configured a DNAT-Rule as follows: when accessing the FQDN-Host "vw.example.de" with port 443 redirect to unraid-server:4743(vaultwarden port). Theres also a reflexive and loopback-rule active for the same NAT-Rule. In Swag I tried a wildcard cert aswell as subdomain only; when checking the swag logs I can see that the certs are successfully handed out. What am I doing wrong?
