SOLVED: Fast Reverse Proxy Rejects Connection

[Delta]

I read the documentation, and there’s a section about using a Reverse Proxy for remote access. I’d like to use FRP (Fast Reverse Proxy). In other projects, TCP works properly.
My problem is that the connection was rejected. I tried to rule out FRPC/FRPS errors:

• Jellyfin is accessible on the local network
  
• Jellyfin is accessible from the FRPC container
  
• Remote connections are enabled in Jellyfin’s network settings
  
• According to FRPS, the HTTP proxy status is "Online"
  
• I haven’t found any error-related logs
  

Here’s what the frpc.toml file looks like:

Code:

serverAddr = "serverIPAddress"
serverPort = 7000

[[proxies]]
name = "jellyfin-http"
type = "http"
localIP = "192.168...."
localPort = 8096
subdomain = "jellyfin"
customDomains = ["mydomain.com"]

Do you have any suggestions? Thank you in advance!
