Gmail configuration assistance - "No DNS record found for autoconfig.gmail.com"

Jeff_Nichols · February 17, 2026, 12:54pm

Hi, I wanted to request guidance or assistance regarding Gmail setup in NextCloud. I’m fairly new with both Docker and NextCloud and trying to setup a server for my family. I’ve been stuck on this for a few days and unsure what to try next. Any assistance is greatly appreciated.

The Basics

Nextcloud Server version (e.g., 29.x.x):
- Nextcloud Hub 25 Autumn (32.0.6) – lscr.io/linuxserver/nextcloud:32.0.6-ls416
Operating system and version (e.g., Ubuntu 24.04):
- NAME=“Alpine Linux”
  ID=alpine
  VERSION_ID=3.22.3
  PRETTY_NAME=“Alpine Linux v3.22”
  HOME_URL=“https://alpinelinux.org/”
  BUG_REPORT_URL=“https://gitlab.alpinelinux.org/alpine/aports/-/issues”
Web server and version (e.g, Apache 2.4.25):
- unknown
Reverse proxy and version _(e.g. nginx 1.27.2)
- nginxproxy/nginx-proxy:1.4.0
PHP version (e.g, 8.3):
- Unknown
Is this the first time you’ve seen this error? (Yes / No):
- Yes, I am trying to setup for the first time
When did this problem seem to first start?
- Never worked
Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
- Docker lscr.io/linuxserver/nextcloud:32.0.6-ls416
Are you using CloudfIare, mod_security, or similar? (Yes / No)
- No

Summary of the issue you are facing:

When I try to setup gmail accounts, the application generates the following error ‘There was an error while setting up your account’

Steps to replicate it (hint: details matter!):

Go to mail
Try to add a new account
Tried both auto and manual configurations. Confirmed that IMAP and SMTP settings are correct for Gmail.

Gmail configuration:

Followed steps to create authentication app in Google auth platform.
I also set the Client ID and Client Secret from Google auth platform into Administration Settings | Groupware

Additional Information:

I know I have duplicate DNS entries in nginx and Nextcloud docker files (above). I did this for troubleshooting. Before and after adding those entries, I could ping external site names and IPs.
I am unable to ping https://autoconfig.gmail.com from any PC on my network and could not ping it within the Docker container.

Google does not offer autoconfig, so the ping goes into the darkness.

Did you configure your Google-accont to accept 3rd party mail clients? - Default is “forbidden”.

Please find the guide at Google:

From Google’s help documentation.

Less secure apps & your Google Account

Starting January 2025, less secure apps, third-party apps, or devices that have you sign in with only your username and password will no longer be supported for Google Workspace accounts. For exact dates, visit Google Workspace Updates. To continue to use a specific app with your Google Account, you’ll need to use a more secure type of access that doesn’t share password data. Learn how to use Sign in with Google.

If an app or site doesn’t meet our security standards, Google might block anyone who’s trying to sign in to your account from it. Less secure apps can make it easier for hackers to get in to your account, so blocking sign-ins from these apps helps keep your account safe.

Use more secure apps

If an app uses less secure sign-in technology, you might not be able to use it with your Google Account.

Apps that use only your username or password will create errors if they try to access your Google Account. These errors can appear as:

“Invalid username”
“Invalid password”
“Unable to log in”

You can sign in to your Google Account from any third-party app that has the “Sign in with Google” option. In some cases you may need to remove your Google Account and then add it again on your device.

Jeff_Nichols · February 17, 2026, 9:56pm

I do not think that setting exists anymore. I do not see it under my Google account settings.

Jeff_Nichols · February 17, 2026, 10:32pm

I get the I.D.10.T award. Everything was correctly configured. Caught that the browser I was using had pop up blocker causing the login prompt from Google to not appear. #ImSoDumb
