Please advise, how to fix this issue
Is the ip address in the error message [203...] your current address? It might be that gmail has flagged that ip address as bad. Have you sent other emails to this person recently or not for some time. Your ip address may have changed in the meantime. You could reboot the wifi router and get a new ip address, or stick it out and see if gmail resets that address at their end.
