I tried to replicate the problem for the video recording and it worked.
I just made some update in plugins and disabled the firewal once again.
So it seems ok now.
Thanks for your help

I disabled it, tried and same json error appeared again.

it was working before, so how can it be host related?

I disables all the extensions and nothing.
I tried with troubleshooting plugin, still nothing.

sorry for my delay. nothing changed. the same error with incognito and new update

the same error when I choose to setup a new property

I creted the stream, so yes I have an administrator account.
I disconnected it and recconected it again before, with no success

In your test site it connects as it should. In my site when I try to choose an existing data stream in GA4 proprty it shows the JSON error, when I choose to create a new one, it stacks in progress bar, without anby results, altought it creates the new data stream.

There are no Rest Api errors and troubleshooting didn’t fixed the problem.
