WAMP Server issue - I check very often (almost every day) and I am sure it was working, if not yesterday definitely the day before.
Checked other topics but couldn't find one with a solution. Cache is cleared.

I can't understand why this is happening...

EDIT: On the live server it works without issues.
EDIT 2: Connecting to another Wi-Fi network showed Site-Key issue. I have changed the Site-Key accordingly and hopefully will work also when back to the previous Wi-Fi. For now it seems to be working fine.

Thank you for the update. Strange changing wifi allowed you to see that the site key was invalid. It's possible your other wifi has a firewall configured that was blocking it? The failed to load error only happens if the HTTP request was blocked entirely.

Ok I am back now and just checked with the original Wi-Fi...issue is back!

No, there is no firewall. Haven't changed anything related to my firewall or Wi-Fi.

Can't think of what might have triggered this. That's really weird...

Only explanation I have is it's a problem with your wifi. There's an outbound firewall somewhere or your traffic is reaching our servers in a suspicious way and is being denied. Suggest checking your wifis settings and comparing it to the one that works.

Will do.

Something I noticed

Is it correct "Your installed version" to be in red in CB Paid subscriptions?


And the "Latest version" not to be in green in CB Control panel?

Both of those are indicating the version checker couldn't reach our servers. Same issue as your install from web problem.
