Vaultwarden: Browser give "ERR_TOO_MANY_REDIRECTS" on initial access to website

(Apologize for not learning markdown. I tried here but failed.)

I am following this procedure (takes you to the failure point):

I did have to (for now!) disable the server firewall because I haven't yet figured out everything it needs. My client firewall is not blocking anything.

Here is /etc/Caddyfile: {
encode gzip

# The negotiation endpoint is also proxied to Rocket
reverse_proxy /notifications/hub/negotiate

# Notifications redirected to the websockets server
reverse_proxy /notifications/hub

# Send all other traffic to the regular Vaultwarden endpoint

Here is the end of the caddy log:

Nothing that indicates there is anything wrong.

I tried stopping file2ban, but that didn't help.

I tried using the RDNS address but got the same error.

Pings all around work fine. I thought there was a DNS problem since I recently changed the IPv4 address and added the IPv6 address in

I tried allowing redirects in the browser. No luck.

Does anyone have any ideas why I might be getting this error?

Thanks. :)

You're assuming that everybody in the Linode-world knows what this "vaultwarden" thing is.

Au contraire…

Given that this is the first time I've ever heard the two words "vault" and "warden" concatenated into a name (and I'm probably way older than you), you're going to have to ask your question about stuff we understand -- web servers, Kubernetes clusters, etc.

I'd suggest doing simple stuff first:

If that doesn't work, try asking your question regarding items that the group here understands.

-- sw

Ok then. I'll just go away.

The linked info didn't help.

And, how am I supposed to know what anyone understands?

I did start out by linking to the Linode Procedure to assist in your understanding.

Thanks for the link. By the way, I'm seeking for essay writing services online to help me do my college assignment, and I came across this website while doing so. This website assists me in doing my assignments and is a really useful essay maker site for students seeking assistance with essay writing services.
