@PeteKnight thanks Pete for the help.
@LanZupancic It’s a known issue, and was fixed recently - https://github.com/blynkkk/blynk-library/issues/553 in the library, but new version is not yet released. In short, the maximum SSID name length is 32 chars (ESP limitation).
@vshymanskyy could we please force new library version update so we get less errors like that?
