Since your connection test was passing on the VPN connection that I had available, I decided to try it once again while connected to this VPN. This time it worked. I am not sure what I did differently compared to the last time - one thing that I did was connect to the VPN and start Steam only after that, that might have something to do with it.

Thanks for the help.

I run the test. It failed on my local connection:

but it succeeded when connected to the VPN I was trying to use earlier, where I had the same issue:

Any idea why it does no t work for me through the VPN?

Thanks.

Hi, thanks for the reply.

I will gladly post the results, but I do not know what connection test do you have in mind. Can you guide me through it?

Do you think it is a problem with ISP or router settings? Did other people solve this problem by changing some settings?
