I have a twice-daily backup script that connects to our managed mongo instance with mongodump and then rsyncs the data off-site.
The command is essentially:
mongodump --uri="mongodb+srv://$USERNAME:$PASSWORD@store-2e6b091b.mongo.ondigitalocean.com/$DB?authSource=admin&replicaSet=store&ssl=true" --gzip --archive="$FILENAME" --sslCAFile=$CA
After running fine for months, a few days ago it’s failing to connect to mongo with the error:
error parsing command line options: error parsing uri: lookup store-2e6b091b.mongo.ondigitalocean.com on 127.0.0.53:53: cannot unmarshal DNS message
Searching for the error message seems to imply that the DNS resolver doesn’t support the
mongodb+srv:// lookup, but I’m not sure why it would suddenly stop working now after working fine for months.
Any help would be appreciated!
