Can't start the Support Panel windows console server error - 403 Forbidden

403 Forbidden error are normally generated by a permission issue for a mod_security rule.

Many hostings added or augmented their Apache mod_security module, adding in several new rules, which if tripped, generate a 403 error.

Removed rule that says: suspicious user agent (desktop app is seen as a web browser, hence suspicious)

If you can't fix this issue, you need to contac your server administrator and request to remove the mod_security rule.
