When is he getting to the point I hear you say

Well the point is this. Since installing it every one of my bookmarked sites including banks, on-line stores, other model rail forums etc shows no difference in the new arrangement and connects just as quickly as before to the desired site. Every one that is except................this site! It just refuses to "see" or connect and eventually times out.
Before I continue, I should point out that I have switched it off temporarily to enable me to post this message. The problem shows itself up using both Firefox and MS Edge browsers. I did manage to get through yesterday after installing Opera Mini on my android phone so that may be a clue to what's going on? But otherwise nothing.
So before I disappear again under my cloak of invisibility (Harry Potter fans will know what I mean) by switching VPN back on again I want to ask if anyone else has experienced this strange anomaly.
Do you use VPN client software (I'm using ipVanish by the way), and if so are you experiencing the same problem?
If you are using a VPN and having no problem, what browser(s) are you using that work with this site?
I'll log back in after Crimble and see if there are any sensible replies
