1. Caddy version (caddy version):
v2.3.0
2. How I run Caddy:
a. System environment:
docker 20.10.5 (API: 1.41) on linux x86_64 Ubuntu 16.04.7 LTS
b. Command:
caddy run --config /etc/caddy/Caddyfile --adapter caddyfile
d. My complete Caddyfile or JSON config:
myfirst.domain.net {
reverse_proxy localhost:32400 {
}
encode gzip
header {
Strict-Transport-Security max-age=31536000;
X-Content-Type-Options nosniff
X-Frame-Options DENY
Referrer-Policy no-referrer-when-downgrade
X-XSS-Protection 1
}
}
mysecond.domain.net {
reverse_proxy /wetty* localhost:3000
}
3. The problem I’m having:
When I open mysecond.domain.net/wetty, I am successfully being directed to localhost:3000. But after the login on wetty (GitHub - butlerx/wetty: Terminal in browser over http/https. (Ajaxterm/Anyterm alternative, but much better)), a “transport close” error appears.
Caddy shows a “connection refused” error in the log.
4. Error messages and/or full log output:

5. What I already tried:
Not much, don’t know where to start.
