403: Forbidden error on update check

I get a 403 error when I check for an update.

PS Is there an option to attach screenshots?

If you Alt-PrintScreen while the window you want to share is active, you can CTRL-V paste it directly in a message you're writing.

I use SnagIt, but it worked. Thank you. I didn't realize I can just paste it into the body.

If blog.dopus.com won't load in your web browser then there might be a regional internet issue.

Otherwise, it's most likely there's a firewall (or similar security tool) on your PC or network which is blocking Opus from making the connection.

No regional blocks, we are not quite a Gestapo state yet as you are guys. :wink:

Nothing on the firewall either locally. I'll check on the network side.

Don't worry about it, I'll fix it myself. Thanks for trying bud.

What could be the problem is that your provider itself is blocking the update connection. Best to check with your internet provider. For instance in the UK BT can block sites that you don't know are blocked. Your provider can do a check and see if that is the case. All else fails do a manual check
