[SOLVED] 255.255.255.255 connection in Chromium

I use ungoogled-chromium-bin with uBlock Origin and uMatrix installed.

I see 255.255.255.255 connection shown in both extensions at XHR field. I have to whitelist in some websites to make them work. I’ve tested it with chromium and it is also shown. In Firefox it is not.

From your experience, do you see it in your - same as me - browsers?

How can I stop this connection with chromium?

Does the problem persist if you disable one of the add-ons? If yes, consider reporting the issue to the authors of the add-ons. But do not expect the bug receiving high priority: if that’s what I described below, it’s only a minor aesthetic issue and fixing it would require coöperation between developers of two add-ons.

This is unlikely to be an actual connection. Looks more like a placeholder, possibly from one of the add-ons. uMatrix displays a similar thing with NoScript, with the  “noscript-csp.invalid” name.

255.255.255.255 could never be a valid IP address of a single host. That’s a broadcast address. Therefore no connection could be established to such an address.

It was NoScript at caused the connection.

For the record it is NoScript version 11.0.9, an old version since the newest version, to this date, 11.0.23 and every other extension I can't install in Ungoogled Chromium.

Also the versions of uBlock Origin and uMatrix are 1.23.0 and 1.4.0 respectively.

Thank you mpan for your responce.
