I’ve been having a connection problem with Gmail that’s been driving me batty (my Dear Wife would say, “It’s a short trip”). I am using Windows 10 Education 22H2 with all the latest updates. I made sure that my bios is up-to-date and I refreshed the chipset drivers on my Asus motherboard. I also reset my network adapters per a suggestion elsewhere in this forum.
When using an ethernet connection to my Fios router, I can send simple e-mails with either Thunderbird or eM Client. But when I send or forward more complex e-mails, such as those with threads or attachments, I usually get the following error message with both clients: “Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again.”
I don’t have any problem if I use a wi-fi connection using a USB TP Link dongle. I also don’t have any problem if I use Linux Mint, which is installed on my PC. (Linux is on a physically separate SSD, which I invoke by manipulating the BIOS, not in a conventional dual-boot configuration.
Both e-mail accounts were installed using the automatic features of the clients that have worked well before.
The fact that Linux e-mail works without a hitch suggests to me that my motherboard ethernet chips are not damaged, and Windows tells me that they are functioning correctly. So that points to software, maybe my OS. So I tried a repair install of W10, which did not cure the problem. I then did a clean install of W10, but that did not help either.
I am stumped and would appreciate any tips you could give me.
Thanks,
Rich
