Do a tracert when it is working and save it.

When it stops working do another tracert. Post them both here.

It may be that sometimes you are connected to a part of the BT network that has a dodgy routing table and so cannot "get to" the servers. Rebooting the router (perhaps multiple times) could put you on a different part of the network that uses a different route and therefore "resolve" the issue.

Thanks.
Have saved a working tracert.

In reply to a post by Jim_AFCB:
(updated every few mins automatically via FTP)

Some web hosts view frequent FTP attempts/logins as an "attack" and triggers the firewall to block the IP address for a period of time, locking you out of all services on their IP address (FTP, email, etc).

I've certainly seen it on some web hosts where I upload a succession of edits in a short period and the FTP times out quickly after a minute or so, forcing me to reconnect each time and trip the firewall limit.

Interesting point.

Never had this issue when on a fixed IP with Sky. It may be that this is a recent change by my hosting company, but wouldnt explain why it only happens on random days. My weather website is updated every 5 mins like clockwork.

I may ask them to take a look at their logs next time this happens.

Might be CGNAT that has some weird intermittent issues with FTP etc.

I thought BT had abandoned CGNAT ages ago.

I also believe it never went beyond a trial.

It fairly easy for the OP to check if they're subject to CGNAT: the WAN address will be in the RFC6898 range 100.64.0.0/10 (100.64.0.1-100.127.255.254)

I know when joined BT 3 to 5 years back we were on it and had loads of issues, phoned BT and they knew we was on it and move us off it and then everything started working.

But not sure if they are still using it or not.

Also try accessing the server as usual then wait for it to break and make a note of your current connection IP and when you can access your server again, check its logs and look for your IP and if it logged see why.
