What is the problem?
New installation of Octoprint. Can not connect. Get error messages on consol:
" Offline (Error: No more candidates to test, and no working port/baudrate combination detected.)
There are also many connection messages: "Server Off line", "Please Reload New Version, Server Available Reload Now?" (Answered YES), " Attempt Reconnect" and sometimes they started over and re-cycled.
In OctoPrint Settings - Serial - the Internet Connectivity Test does not work. The Resolve Name does work.
What did you already try to solve it?
Tried connecting with IP address and with Octopi.local and both connected.
Tried setting fixed 9600 Baud rate.
Changed cables. Changed Pi power supply. Put tape on positive USB contact.
Checked to see if I could log on to Pi OS with this network installation with Putty and I could.
Have you tried running in safe mode?
Yes
Did running in safe mode solve the problem?
No change. Except for message - Running in Safe Mode
(I don't think Pi was running anything at all).
