1. Caddy version (caddy version
): Caddy:2.4.6-alpine
2. How I run Caddy:
a. System environment:
b. Command:
Paste command here.
c. Service/unit/compose file:
Paste full file contents here.
Make sure backticks stay on their own lines,
and the post looks nice in the preview pane.
d. My complete Caddyfile or JSON config:
cloudname-develop.westeurope.azurecontainer.io {
handle_path /service1/* {
reverse_proxy localhost:8080
}
handle_path /service2/* {
reverse_proxy h2c://localhost:8081
}
handle_path /service3/* {
reverse_proxy localhost:8082
}
}
3. The problem I’m having:
I am trying to setup up Caddy to reverse proxy to our GRPC service that is run in docker, at localhost:8081.
When ever I try to hit the service we get a unexpected EOF error in the Caddy log and nothing comes through the service.
4. Error messages and/or full log output:

5. What I already tried:
I tried doing it this way as well just for a test without needing specify the service name. Same issue
cloudname-develop.westeurope.azurecontainer.io {
reverse_proxy h2c://localhost:8081
}
