I'm on my 3rd day with astroberry on a Pi 4 8GB. I installed the latest image (vs. the more manual install). I'm seeing some oddness that I hope someone can shed some light on.

For instance, iOS connectivity (iPhone and iPad) to the astroberry seems very iffy and has stopped altogether as far as noVNC in Safari. I get the start screen but on the connect screen, when I press connect it fails with the red banner. It is possible that the one time it worked was before I disabled ipv6 on the Pi (although ipv6 has always been disabled on the router).

VNC client app works fine on ios.

Chrome in Windows works fine (except I can't figure out how to copy and paste) and VNC clients on windows also work fine.

I have not made a self signed certificate.

FYI in working with webserver/clients in my home network before I've seen odd behavior until I disable ipv6. ipv6 is disabled on the ASUS router and on servers and clients, including the Pi, except you can't do that on iOS (apparently cellular networks are mostly ipv6 these days?). Turning off cellar data on the ios devices doesn't help and perhaps the whole ipv6 thing is a separate issue from the NoVNC on ios safari anyway but I thought I'd mention it, as it also acts like intermittent connectivity (until you defeat ipv6).

 

OK for that that come after;

1) There is a buggy behavior with certain ASUS routers where WiFi clients connected at 2.4 GHz and 5 GHz can't reliably communicate with each other (although internet connectivity for both is fine). The solution is to turn off "Airtime Fairness" (I did it on both bands):

2) On the iOS devices, it is important to use http vs. https, in order for noVNC to work. Either will get you the start page, but at least for me, only http will work to connect VNC.

3) If you are having trouble getting your Pi to connect via 5GHz (and you are close enough to the router for 5GHz) make sure you have your network localisation set properly. Your Pi needs to know what country you're in so as to know what the correct frequency bands are to 5GHz WiFi.

Whew!
