### Description

I have a problem with running the https connection. Everything worked well and it stopped after LetsEncrypt failed to update the certificate.  
Currently, everything works with an unencrypted connection ([http://myserverdomain:8080](http://myserverdomain:8080)). The new certificate files are defined in the Caddyfile (wildcard certificate) and are loaded correctly. When I try to change the configuration in Caddyfile to https, I get the “502 Bad gateway” error.  
I do not know how to fix it.  
I do not know linux very well, so I am asking for an easy answer 🙂

Current Caddyfile configuration:  
http:// myserverdomain:8080

# tls ./cert.pem ./key.pem

proxy /localhost:3000 {  
WebSocket  
banner  
}

Configuration with encryption enabled:  
https:// myserverdomain  
tls ./cert.pem ./key.pem  
proxy /localhost:3000 {  
WebSocket  
banner  
}
