are webhooks supposed to work on ports other than 80?

Good day,

I have a webhook which works fine. A Workflow trigger calls my web service which is on port 80.

But when I put my web service on port 85 (and of course I update the Webhook to call http://myservice.com:85/myservice), it no longer works. I get "HTTP Response - 1" in the Webhooks Failures log. I am able to call up the web service on port 85 using other tools like curl , so I know it is working correctly. But Zoho CRM does not seem to call the web service on port 85.

Are web services other than port 85 supposed to work? I've looked through the documentation but find no reference to any port restrictions.

By the way, it also seems that the "Links" feature does not work if the link being called includes a port number that is not 80 (i.e. http://yourservice.com:85/yourservice).

Thank you -Ricardo
