Support intro
- Nextcloud version :
30.0.1.2 (docker)
- Operating system and version:
Debian 12
- Apache or nginx version:
2.12.1 (docker)
- PHP version:
8.2.25
- Other information such as config.php, compose file, and npm config are all at the end of this post.
My nextcloud periodically generate the dns_get_record error below everyday:
dns_get_record(): A temporary server error occurred. at /var/www/html/lib/private/Http/Client/DnsPinMiddleware.php#96
(My nextcloud.log here)
Recently, I changed to another IP and router to to see if it’s my router’s issue, and I have noticed another type of warning also got generated (shown below). It might be related to the error, but I’m not sure how to debug the issue.
LocalServerException No DNS record found for apps.nextcloud.com
LocalServerException No DNS record found for download.nextcloud.com
issue while running UpdateSingleMetadata
(My nextcloud.log here)
Here are the things I have tried yet not solving the problem:
- Since I’m also using IOTstack to start my docker-compose file, I have tried adding
--dns 1.1.1.1
into my docker-compose file like the post Error: dns_get_record(): on first run suggests. - Change DnsPinMiddleware.php like this git issue Log flooded with “dns_get_record(): A temporary server error occurred” suggests. This git issue mentions that Debian has another issue (#3 below)
- Change /etc/nsswitch.conf to
hosts: files dns myhostname
like this git issue ( Intermittent DNS name resolution failure, likely IPv6-related)
I’ll continue listing the things I have tried but if anyone knows what’s the issue or what I could have do better to debug this, please let me know. Thanks.

# Specify how to handle directories -- specifying `/index.php$request_uri`
