So today I'm getting this message in Gmail only when attempting to send. I can still receive just fine. I had made no changes to my account.

The message (s) could not be sent. Check that you have network coverage and that your account information is correct. Then try sending again.

I've rebooted my phone soft and hard.
Although I never touched my settings I checked them anyway.
I went to gmail on my computer and logged successfully with my password (had previous issue with this) logging in from PC resolved it, not this time.

I'm stuck. Don't know what else to check. I knew it would F up eventually. Any ideas?
