The new arduino 1.8.10 has problems. I updated to this and previously compiled sketches will not compile. I reverted to 1.8.9 and all is well again.

There is a lot of posts on arduino about issues with 1.8.10. - I am using the win 10 x64 version.

Thanks @Tag

Seems that to get Java updates now you need to register with Oracle and give them all your details including work phone number and job title - why they need this I don't know.

So does anyone know where to download the latest JDK8U231 for arm without exposing all my personal data?

@Tag Haven't had much time to look into this as yesterday was my Birthday and I'm still drinking as I type tyis!!!!!....

@Tag Thanks for the thought, but all are type status, data binary. I am sure this has happened recently as I remember them being fine before. Maybe an update has upset something?
Ya gotta admit it's a bit strange for a 'binary' to have up to 5 levels - maybe it's a secret quantum code JK is using here?

@jkandasa All of them! -Look at the vertical y-axis and see the strange numbering system used. They should all be 0 and 1 only.

The graphs used to look normal, but recently strange things have been happening - Can anyone guess what is going on here?

Once again I am baffled!

@Tag I dont use chrome but maybe you need to install the cert somehow? ??? Perhaps this is different to a url based cert? who knows? It's all I can think of at the moment

@Tag Pity - I was clutching at straws that maybe https was blocked on non-standard port or a firewall blocking on non-standard ports.

Ah well, we tried.

I am fresh out of any other suggestions as this is beyond my experience.

Sorry

@Tag Maybe it's the firewall on your router or an isp thing.

Try connecting from the internet on port 443 and then forwarding that to port 8443 to the server. Worth a try to see if the issue persists?
