Powerquery | Web.Contents timeout when TLS connection is not already stablished

Hello AmiraBedh, thanks for helping. I verified Internet options and old protocols are disabled. I've tried also disabling my firewall but it fails in the same way.

Regarding the timeout of 5 seconds, putting a higher value does not cause any changes. In fact, I tried setting 2 minutes and in that case the server closes the connection, as expected.
I think if there was any problem during the TLS handshake I would see it through Wireshark, but I don't.

On the other hand, I've tried with an https API using GET method and there is no problems. I'm starting to think if the problem could be related to POST api calls only. But it's strange because in another computer (Win10) with same Excel version I don't have the issue.

Thanks!

Santiago.
