MongoDB connection not working

[AronC]

We have a connection to a Mongo db database from a Qlik cloud tenant. The connection has been working fine for over a year. Since the ninth of November 2023 it stopped work for us without having done any changes.

When I try to connect to the data connection I get this error code:

"ERROR [HY000] [Qlik][MongoDBODBC] (110) Error from MongoDB Client: No suitable servers found (`serverSelectionTryOnce` set): [TLS handshake failed: certificate verify failed (20): unable to get local issuer certificate calling hello on 'mongo-XXX-biconnector.rdcqh.mongodb.net:27017'] (Error Code: 13053)"

I had a meeting with the dba of the MongoDB-database but he couldn’t see anything bad in the configuration from his side…

Anyone that has any ideas?

how you are connecting use  some kind of certification or ODBC?

May we know how you are connecting to Mongodb. ? are you providing any certificate or just setting TLS=true and providing username/password?

if you are not adding any certificate, please just check "Ignore Certificate Validation" option . Let us know if it worked now.

Thanks,

We are not using certificate but How to check whether we enabled TLS= True or not?
