Auth fails with mongodb atlas cluster

[itzmanish]

Describe the bug
"connection() : auth error: sasl conversation error: unable to authenticate using mechanism "SCRAM-SHA-1": (AtlasError) Authentication failed.

Everything was working fine till today I get error with authentication failed. I didn't changed anything, not a single line of code but still I get error on any operation with mgm connection() : auth error: sasl conversation error: unable to authenticate using mechanism \"SCRAM-SHA-1\": (AtlasError) Authentication failed.

To Reproduce
Steps to reproduce the behavior:
1.

err = mgm.SetDefaultConfig(nil, "directory", options.Client().ApplyURI(os.Getenv("MONGODB_URI")))
if err != nil {
	log.Fatal(err)
}

2. Export MONGODB_URI with mongodb atlas cluster uri.
3. Run the server.
4. Do Some operation.

Expected behavior
Operation should complete without any error.

Environment (please complete the following information):

• OS: Ubuntu 20.04

Hi @itzmanish

Please check you authentication data by login manually to you DB, I think this is because of wrong AuthenticationDatabase or username|password in your DB URI.
Maybe you enabled authentication recently in your Atlas cluster and you should check your DB authentication data.

Not the case. I was using for a long time with same setup.

However something weird I have seen that official mongo driver gives me same error but when I pass credential option with username and password it works. Don't know why this issue didn't occur before.

Print your URI before connection, maybe it's not what you expected.
I'll close this issue, but if you need some help, comment here.

URI is fine. I don't know why I need to use credential option since I have username and password in URI string.

Just like this?
mongodb://{username}:{password}@{your host}:27017/{yourdb}?authSource={admin or your authentication database}

use command line command (like mongo "mongodb://test:testpwd@localhost/test?authSource=admin") and check it, because I think just URI can cause this error.
