Thanks for that, a little mangle rule on the mikrotik router at the front and all seems to be ok on that test (only checked on the phone, and haven’t checked any of the websites yet) … can’t attach the image from the phone for some reason either!

I have just tried the problem website from Tuesday on the PC and the suggested fix has solved it!

Thanks very much

Great news.  Those IP6 MTU issues are painful.
