So, I appear to be going in circles. I'm going to stop where I'm at, and stick with what I have, but I need to get an issue resolved.
I've torn down the cloudflare tunnel and went back to port forwarding, using a reverse proxy with nginx, and cloudflare. Here are the steps and the settings I've used.
setting up cloudflare: I already had my domain moved over and handled by cloudflare, so I didn't need to do anything here, but my first step was to setup new api token. within cloudflare I clicked on profile>api tokens> create token > edit zones > change token name > zone resources > all zones > continue to summary > create token.
it was at this stage I copied the test and pasted into the unraid servers terminal. It appears to have passed with no issues. I copied the api token.
setting up nginx: installed nginx on unraid. I updated the HTTP and HTTPs ports to 1880 and 18443. luanched the UI and first step was to create a ssl certificate. Add ssl cert > lets encrypt > domain names > *.domainname.com > email address > use dns challenge > provider > cloudflare> inserted api token from cloudflare
setting up vaultwarden: installed vaultwarden, simply set signup to true.
setting up cloudflare ddns: installed cloudflare-DDNS. configured it with my email that associated with cloudflare, set the doman, and provided the global api key from cloudflare's website. clicked done. Went to cloudflare and verified that the A record has been created.
setting up reverse proxy: visted cloudflare > clicked on domain > dns records > added cname for warden
next I went to nginx proxy manager and added a new proxy host.
after which I click on the link and I get this error
if I click on docker and select webui, I'm now able to gain access to the vaultwarden admin, thanks to @yogy's suggestion for updating the admin token. However if I click vault, I get a login, but when I attempt to access it with my password. I get this error.
which doesn't make sense, as I believe I've configured my reverse proxy correctly.
Any insights?
