I have some ESP-01s and they were all working fine until after I updated the board manager to yesterday's version. Now when a virtual AP is created, the 192.168.4.1 returns no webpage and times out. (100% sure its the right ip, I scanned the network to make sure)
When I go to my other computer with the few days old version of the Arduino ESP plugin, the same code, making a softAP, and visiting the website at 192.168.4.1 works fine...............
