I tried many times, on RPI3 and 4, on SD card or SSD, from different PCs, and even with a supervised install. Always the same, start OK, but connection impossible after a few minutes. I googled the pb, but can’t find any idea on that. Any clue for a desparate and lost french man ?.. Thanks for your help Christophe ChrisDest August 13, 2026, 6:22pm 2 The message is “ERR_CONNECTION_REFUSED” when I can’t connect fleskefjes August 13, 2026, 6:58pm 3 With little information to go on and no logs, I would say your network or DNS is what I would start looking at
