Nat loopback stopped working, again!

Have been running my own Web server for private use for years. Moved to Vodafone 4 years ago and had issues initially which eventually were resolved.  Overnight the router restarted and this morning I'm unable to access my website from the Vodafone WiFi.  If I switch over to mobile Internet it works fine.  When I put in the domain name that should be my website, I get the router login page.  The issue is Nat Loopback, but there isn't a setting to enable this on the router, so it's being switched on and off by firmware updates.  Trying to speak to support and they don't have a clue, as long as you can access the Internet according to them its fine.

@dmfarrow  What is shown in the logs?

Have you tried turning off all references to IPv6, if it is on?

What, if any, are your DMZ settings?

Have you tried a factory reset?

Can you access it using a wired ethernet connection?

What is the router software version number?

IPv6 all disabled, DMZ isn't used, specific ports set to forward individually, Router firmware is 19.4.0551-3261143

Factory reset is next option, but it's a pain to reset all the SSID and forwarding as the Web interface to the router is painfully slow.  Need to set aside an hour to do that.

@dmfarrow  I wonder if the forwarding rules are not working, what did the log show?

Forwarding works fine from outside the network, inside just gets the router login screen.  The logs are pretty much unreadable as the page takes so long to load.  About to renew my contract so will probably go down the Ultra route and get a new router.

@dmfarrow  Do you have a lot of devices or a few high traffic devices connected that could be overloading the router so that you get this slow response? I had never experienced that when I used it, but there are other complaints on the forum so I know it's a thing.

There's nothing unusually high load, but there are a large number of smart lights, sockets, Alexa devices.  Nothing huge, but around 40.

That is a later firmware than has been reported on here previously, so perhaps they have deliberately made the change.

As it is just from your own LAN could you not just use the I.P. address?

@Jayach Another new version. That's interesting.

Isn't it. I really wasn't expecting any more.
