Gmail "NS_ERROR_NET_INADEQUATE_SECURITY" on Thunderbird 78.11.0 (64-bit) on Debian 10 LXQt

Greetings Forum:

After an upgrade, I noticed my Thunderbird installation on Debian 11 LXQt was no longer able to update email for any of my previously configured gmail accounts. Non-gmail accounts on the same TB installation are unaffected. The bottom window where I normally read emails shows:

Your connection is not secure

The website tried to negotiate an inadequate level of security.

live.thunderbird.net uses security technology that is outdated and vulnerable to attack. An attacker could easily reveal information which you thought to be safe. The website administrator will need to fix the server first before you can visit the site.

Error code: NS_ERROR_NET_INADEQUATE_SECURITY

I have not made any changes on the gmail side and I can still access the gmail account directly via WUI as well as my android app. Does anybody have any suggestions?

You reported way back that you could not connect to live.thunderbird.net. Guess where the settings are stored?

i posted a suggestion on the bug that was filed for this issue. Perhaps try that. https://bugzilla.mozilla.org/show_bug.cgi?id=1716320

I can confirm that on a fresh installation of TB 78.11.0 on a VM that I can login and authenticate my gmail account when setting up a new account from scratch. However, my everyday computer has a TB installation with hundreds of filters, numerous email accounts, and I certainly do not want to go through setting all of this up from scratch just to fix this problem.

Is there any way to make Thunderbird prompt for a new password via Gmail's authentication method without deleting the account?

Did you mess with the TLS prefs in about:config?

christ1,

Thank you for your reply. No - I have made absolutely no changes in the installation. I even compared the default settings on my trial VM installation where I setup the account from scratch and my recently upgraded version with the problem side-by-side. All settings are exactly the same.

I just need to figure out how to force Thunderbird to re-authenticate the gmail account through the typical Gmail popup that normally occurs when creating the account for the first time..... Any ideas on how to prompt this from TB?

This is not a password problem, so it won't help to re-authenticate.

I'd assume you're using the Thunderbird version provided by your distribution? Is the Thunderbird version exactly the same on your 'everyday computer' and the VM? My bet would be on a faulty Debian update. Did you ask in a Debian forum? You may also try the vanilla Thunderbird version from https://www.thunderbird.net/

Yes, using the preinstalled version of Thunderbird on both machines. Yes, using 78.11.0 on both.

I am sure I can delete the account on my every-day machine, re-add the gmail account and it would work. I've done this on several VMs now just to test, and it works everytime. But something happened after a recent update that is preventing my everyday machine from authenticating correctly with Gmail.

There is at least one other person that is having this same problem today as well: https://support.mozilla.org/en-US/questions/1340573#answer-1421505

So I have located one of my gmail accounts without any complex message filters that was previously configured in my Thunderbird installation. I made a backup of the data in /home/user/.thunderbird/!@#!#.default-default/ImapMail/imap.gmail-02.com/ and deleted the account.

Now, when I try to re-add the account from scratch, I get an error message "Thunderbird failed to find the settings for your email account."

I tested it (change the value of security.tls.version.min from 3 to 1) and it didn't change anything

Matt's link above helped me solve this issue connecting to Gmail accounts with TB 78.11.0. I'm not sure about outlook.office.com, but if you are receiving the "NS_ERROR_NET_INADEQUATE_SECURITY" error, give this a shot:

Click the three horizontal bars to display the main menu in upper right hand corner Preferences>Config Editor (either scroll down or type "config editor" in the search bar) Click "I accept the risk" Type into the search bar: network.http.spdy.enabled.http2 Double-click the entry to toggle from true to false

Gmail is working again!

Matt - THANK YOU for the link! Setting network.http.spdy.enabled.http2 to FALSE did the trick! For others with this issue, here's the step-by-step:

Click the three horizontal bars to display the main menu in upper right hand corner Preferences>Config Editor (either scroll down or type "config editor" in the search bar) Click "I accept the risk" Type into the search bar: network.http.spdy.enabled.http2 Double-click the entry to toggle from true to false

Changing network.http.spdy.enabled.http2 to FALSE worked here as well, and I didn't even have to authenticate even though in the meanwhile I had deleted and re-created the gmail account and deleted the gmail passwords. Many thanks.
