Do you have anything different about your NR setup we should be aware of?

[Paul-Reed]

It's pretty much a standard install, and regularly updated, both only using the RP script.
I can't think of anything 'different' from 'out of the box' other than settings.js is owned by root & https is enabled.
The dashboard has been used since the very early days of DB2, no errors in logs & no other problems that I'm aware of.
The layout used in that example is 'fixed'.

[Paul-Reed]

In the node-red-log, this is what I get when I try and save the changes;

Hi Paul.

i see from your screenshot the URL was xxxxxxxx.co.uk do you have local access to try this via IP address?

Platform/OS: Ubuntu 24.04 Cloud

Where is this running? locally? on a cloud platform?

Do you have any other devices you can test this on?

[Paul-Reed]

do you have local access to try this via IP address?

No, not without a number of changes (ssh enforced - cloudflare)

Where is this running? locally? on a cloud platform?

It's a Oracle remote cloud server

Do you have any other devices you can test this on?

I also have a 2nd Oracle cloud server which I've just tried, and get the exact same result.
I've just updated both, to be the same versions, and also updated/dist upgrade both operating systems.

both servers

@Paul-Reed ,
I see that @Steve-Mcl has merged some pull requests related to this issue.
Does this mean your problem is now solved, or am I mistaken?
Thanks!

[Paul-Reed]

I haven't closed it because Steve has linked this to close via #1488
But yes, can be closed, issue fixed.

[Steve-Mcl]

It should have auto closed when merged to main.

Closing now.
