Hi Ines Are you trying to setup gmail in TBA for the first time, or was it working before and now stopped? Are you using Outh authentication? Normally your directed to googles sign-in page to grant the app permission to access your account. Are you seeing the network error after completing the sign-in process? I've attached a screen shot of the SMTP settings from my working gmail. You can compare this with your settings found under settings > account > sending mail > outgoing server. Do the Imap settings connect and authenticate successfully? If your using any VPN, Antivirus or security apps on your phone, try disabling these. Do you have the same issue on wifi and cellular internet connection?
