MvCall and odd port...

[wmgilligan]

Trying to use MvCall to connect to port 7470 (required).
Works fine as a straight URL in the browser, but MvCall is always "Error connecting to dev.fffxxxffx.com on port 7470: Connection refused".
Ideas?

Perhaps that port has been firewalled from the location Empresa is located and running the script?

[wmgilligan]

I am checking on that. Thanks. MvCall doesn't require (or have) any special port settings does it?

No, I would expect it to work.

[wmgilligan]

Hmmm... you may have hit on something... checking that to...

[wmgilligan]

Nope - outbound is wide open. Good idea though.

What about incoming connections from the server Empresa is located on? I.e. your IP is whitelisted but the IP from the server where Empresa is running is not? Are you making a GET request via MvCALL too?

[ILoveHostasaurus]

We're referring to inbound firewall on the system accepting the connection from you; Empresa is getting an active connection refused, so something between it and whatever it's trying to hit is rejecting the connection attempt at the TCP level.

Yes - doing an MvCall GET and using headers, etc... I can run the call just fine from a local machine, but from the server - dead stop. Seems to me that their end is blocking things. I have checked all our inbound and outbound rules. We are also behind a load balancer - but all other mvcalls work fine. The only real difference with this one is the port we need to hit.
