No more free sessions

I'm running RRF 3.5, WiFi server 2.1.0 and DWC 3.5.1 on my Duet 2 WiFi and the connection keeps dropping and I get a red message saying "Failed to maintain connection to foo.local" and "No more free sessions". Then a password prompt pops up. If I reload the web page, it works for a few seconds or minutes, but then it happens again. Has anyone else seen this?

@tomasf how many different clients are you using to connect to the machine?

One. Just a single browser tab.

@tomasf which OS and browser?

tomasf

@dc42 Safari on macOS 14. I have not seen it happen with Chrome.

Can you try increasing the AJAX retries on the Settings -> Machine-Specific -> Communication panel to e.g. 4 or 5

@Phaedrux I put it at five, but it seems to still be happening.

@tomasf It sounds like the web interface keeps losing the connection and attempts to create new sessions too frequently. Can you please do the following:

Try to connect using the IP address (get it via M552)
Open the browser dev tools via F12 and check if there are HTTP 503 responses

Do you have a PanelDue as well?
