I've been trying out the newly introduced Web Tabs feature in Zoho Mail, but unfortunately, I haven't been able to get it to work not even once.

Every time I try to load a webpage within a Web Tab, I get the following error message on my screen: "mail.zoho.com refused to connect."

I already tested it with several different URLs to troubleshoot:

Regardless of the URL I use, I always get the exact same "refused to connect" error:

Has anyone else successfully gotten Web Tabs to work? Are there specific settings, either on Zoho Mail or in the websites that I need to adjust to allow these connections?

Any guidance or troubleshooting steps would be greatly appreciated!
