Firstly, sorry if this is covered in another post, I’ve scanned and found many discussing similar things, mainly wireless connection issues, but nothing that has helped (although they have given me ideas for things to check, but still I am where I am)...
I'm really not an advanced user but I have managed to setup myself an RPi, configure it with OctoPrint and connected to my Prusa MK3S+ and I have the following situation....
When the RPi is connected to wired LAN, I can load the OctoPrint login page and connect via Firefox (remote Ubuntu machine) using the local RPi IP 192.168.0.xx or the octopi.local url, all is well. In this instance I'm not using SSL (just http://) - [I’ve looked at the guide I found on here to setup SSL and try as I might, I’m not following the instructions, sorry.]
When I disconnect the LAN from the RPi and connect the RPi to my wireless network however, Firefox refuses to load the OctoPrint login page, nothing happens, just a timeout eventually (using either url mentioned). Same result on a Mac using Chrome browser.
At this time, I can ping the RPi and I get a response, so I know it's on the WiFi network.
I can login to my OctoEverywhere account via the same browser and see the printer is online.
I've also ssh'd into the RPi and checked the regional and wireless setup/config which all looks good, to my eye / aligns with the guide I found posted.
When the RPi is on the wireless network I can also connect to my printer from Octopod on my iPhone, using the above mentioned url and I can see the video stream/control the printer.
Maybe some might say just leave the RPi on the wired LAN then but it’s not really convenient by way of LAN port connections in terms of the positions and, when the RPi is connected back via wired LAN again, I can still connect from Octopod on the phone, but it's unreliable (I get lots of cannot refresh errors) and the video stream doesn't work.
So, why is a wired or wireless connection on the RPi causing such variable connection behaviour, primarily why cant I connect from my laptops browsers when the RPi is connected to my wireless home network, using only http. What can I do to get it working?
Some simple hints and tips for dummies’ based suggestions would be so much appreciated. I’m really confused.
