SSL Hanshake Failure, User authentication Failure and a series of other failure

Shubham_Sharma6 · September 20, 2021, 4:14pm

Hello,

We have a flask based server which interacts with the Atlas cluster. we have noticed that the server keeps going down again and again at random intervals.

After investigation, we noticed that we are getting multiple ‘AtlasError’ in our logs. We have various types of pymongo.errors.

pymongo.errors.OperationFailure where the user account is not found.
pymongo.errors.ServerSelectionTimeoutError:
pymongo.errors.NetworkTimeout: SSL handshake failed:
pymongo.errors.NetworkTimeout: SSL handshake failed:
pymongo.errors.NetworkTimeout: SSL handshake failed:
pymongo.errors.ServerSelectionTimeoutError: SSL handshake failed:

And various similar issues.

Please note that once we rebuild the environment and reset everything the connection is established and then again after sometime these errors start occurring and the system goes down.

Driver details :
Have tested this with pymongo 3.7.x, 3.11.x, 3.12.x

Using this with client configurations as follows:

pymongo.MongoClient(<connection_string>,
   authMechanism='SCRAM-SHA-1',
   connectTimeoutMS = 4000,
   serverSelectionTimeoutMS = 4000,
   socketTimeoutMS = 4000,
   appname = '<app_name>',
   retryWrites = True,
   retryReads = True,
   readPreference = 'secondaryPreferred',
   #tlsDisableOCSPEndpointCheck = True, ##Try deploying with this also.
)

In this, we have tried different timeout values ranging from 5-30 secs. And we have recently put out a version where we have succumbed to disabling OCSP Endpoint checks (which we wouldn’t like to continue with since its a huge security risk - we have done this for the time being to see if it keeps the server up for longer).

Regards,
Shubham

Hi thanks for opening this issue. Nothing stands out yet as an obvious culprit to me. Please provide the full traceback and full error message for the various exceptions you are experiencing. You can redact and sensitive info like host names or user names.

Please also provide the output of pip list so we can determine if you are using PyOpenSSL or not.

Can you also describe what server product (atlas dedicated, atlas free tier) and version (MongoDB 4.0, 5.0, etc) you are using?

We are using MongoDB Atlas M10 cluster. Initially this was an M0 where we noticed this issue. We thought this could be a network issue due to shared hardware so bumped it up to M10. The server version currently is 4.4.8

Please let me know if you need any more details.
