Azure Windows VM doesn't fully load certain websites

I've noticed certain websites don't fully load on my Azure Windows VMs.

I've got 2 examples

  1. bet365.com - page loads initially but then just tries to load forever.

  2. picuki.com - when making a search on the website it also tries to load forever.

I tried changing the DNS settings on Azure, but it made no difference no matter what I set it as. I really know know anything about networking. So here is a screenshot of my inbound-outbound rules in case that is the issue.

Does not make sense, AFAIK there´s no filtering... have you tried to Update de machine ? BTW the inbound loadbalancer is needed for this machine ?

Issue has been ongoing for a while. As far as I know these sites have never worked since I created the VMs. So don't think it's an update issue. I haven't got a load balancer do I need to create one?

Hi @ChipchaseMatthew-3022 ,

in my opinion your experience is happening due to default security settings on windows, more specifically on your Web Browser, IE or Edge.

Perhaps you could first get some clues from your browser Web Developer Tools, and when you request a webpage, you could see what URLs are being blocked. Probably some sites are calling other sites and your Browser security settings are blocking cross-site calls. Something quite common.

Let us know!
Best regards,
Juan

Hi there.

Yes, a bit. I'd like to see the details of the first error. I can see a truncated message "(failed net:ERR_CO...".

I would look at:
https://www.ionos.ca/digitalguide/hosting/technical-matters/err-connection-refused/

I saw you opened at least one more thread:
https://docs.microsoft.com/en-us/answers/questions/33097/cant-connect-to-specific-website-on-azure-vms.html

Furthermore, I can see this discussion from another user, she had very interesting answers. Worth to check.
https://answers.microsoft.com/en-us/windows/forum/windows8_1-networking/errconnectionrefused-error-when-accessing-few/cdf62e68-ebb9-48ad-b9bd-d2042f778fbc

The last, but not the least, perhaps you could try first a wider rule, such as

Source: Virtual Network
Source Port Range:
Destination: Service Tag
Destination Service Tag: Internet
Protocol: Any
Action: Allow
Priority: 4096
Name*: Allow-AllInternet

And take it from there.

The error is ERR_CONNECTION_REFUSED

I've tried disabling Windows Firewall and my antivirus software, but that made no difference.

Also tried setting the wider rule like you suggested, but again made no difference (I rebooted and cleared browser cache)

There are no proxy settings set.

My previous thread never got resolved, hence this new thread.

Tried everything from that other thread you sent and nothing has worked either :(

This didn't make a difference. Issue still the same. Is this the correct way of setting it?

I also have the same problem.

I believe that Bet365 blocked VM IPs to access the site.

I see no other way, if not the block from it.
