I mean, I have the exact setup I described (well, the UC_CK is on eth2 of an ERL...), and it's not throwing any errors.
In the end I could find the error!But what a mistake, more idiot.
It turns out that I use the Ublock Origin advertising blocker in all browsers, and in the IP addresses I was using for all the tests and all the accesses, I had it disabled.
In the end I had to deactivate the advertising blocker at the root, from inside the browser, this is how I could access without any problem.
What a job he has given me!
And sorry for all the inconvenience that I have foolishly caused.
A cordial greeting.
