Car4Play - No FM2R

I'm in Vienna using WiFi and mobile data, nothing special about either of them and they both work flawlessly with everything else I do. I am using my laptop and my telephone pretty much equally, both use WiFi and mobile data.

Repeatedly Car4Play is unreachable and I have to try several times before it will connect. It can happen at any time without logic, and is happening half a dozen times a day at least.

I did not have this problem last eek in Madrid, and I have not had this problem in Chile.

Any ideas? Not a catastrophe since it always eventually connects, but kind of a pain especially if one has written a long post.

its been fine here all day, As its location specific I would suggest its the ISP DNS

We are however grateful to the ISP your longer posts got truncated.

I's been several days. Given that it is Mobile data and WiFi I suspect that it is not the ISP.

Still no biggie, and if it's just me I shall ignore it.

If the mobile and wifi is the same telco, it could be the DNS. you could always do a Tracert if you are curious

Tracert is going to be a right PITA with an intermittent fault, I think.

Thanks for the suggestion but I guess I'll just live with it.

tracert might not work anyway. Quite a few gateways drop ICMP ECHO requests in the bit-bucket as a partial counter-measure against DDoS. Either that or give them to a sacrificial server to respond to.
If it is local DNS problems try changing your DNS server to Google or Cloudflare's public service. (8.8.8.8 or 1.1.1.1).

Right. That's clear then. I'll try it :-)

Say again. Was it 4 sand and 1 cement? My word, I am 'out of it'.

It is (was) a DNS problem, though I am not entirely sure why or perhaps how. Changed to Google's DNS server and it appears to have gone away.

MD - it means the bit that tells my computer where to find another computer is either confused or wrong. So I use someone else's bit which is a bit more on the ball.

Just to report that I’m getting a certificate error when trying to connect via some devices.

Sounds like something expired at end of Sept!

Which device types zippy? It's OK on my PC and my Android

..it's OK here, and the certificate is reported as renewed at the start of September.

I wonder (given Zippy's comment on DNS servers) whether this is a throw-back to the migration and certificate work in January.

If the private DNS has not been updated or has been refreshed in error, and the old version of the forum is still reachable, then there would (I think) be certificate errors. It would only apply if that access hadn't been used since the change, or if the private DNS server had somehow had the address reverted.
