Websocket: bad handshake

[Madic]

The problem “magically” disappeared at some point. Running rancher(-agent) 2.2.6 at the moment. But got another problem:

Let's encrypt certificate on rancher-server: unable to get local issuer certificate

Hello, I try to register a rancher-agent, running on RancherOS, against a rancher-server with a certificate from let’s encrypt but the agent fails with the error: “Failed to connect to proxy” error=“x509: certificate has expired or is not yet valid” The problem occurs behind traefik as reverse proxy and beeing directly exposed. My docker-compose file for rancher-server: version: '3.3' services: rancher-server: hostname: rancher domainname: example.tld container_name: rancher-serve…

I do not have a working environment since…forever because of these problems.
And nobody is responding with some help…
