ZTNA - no healthy upstream

Leonardo Mota

Hello.

I`m using Sophos Firewall as a Gateway.

Im trying to access a agentless resource using ZTNA, the configuration process was OK and the DNS configurations OK as well.

When we try to access a resource that is on port 9001  we get a no healthy upstream. 

Authentication is happening fine before accessing the resouce and the internal FQDN leads to the internal IP. 

Maybe im missing something in the Firewall to let access by to those ports?

    Is the resource HTTP or HTTPS based? Did you check if It's configured correctly at Sophos Central? Mismatching the protocol can cause a "no healthy upstream" error.

    Can you send a screenshot of the resource, showing it's configuratios?

    Also, you can verify if the Firewall has connection to the resource by SSH'ing to the Firewall, going to advanced shell, and doing a "curl -v resource.domain".
