This issue was previously (#6774) and fixed, but appears to have been reverted in v2.2 (#7116).

For this issue, it is recommended that the following be done:

from typing import Annotated

from pydantic.networks import UrlConstraints
from pydantic_core import MultiHostUrl

MongoSRVDsn = Annotated[MultiHostUrl, UrlConstraints(allowed_schemes=['mongodb+srv'])]

[samuelcolvin]

yes @as per #6774 @hudrazine's solution is correct.

Ran into this problem today. Should this solution be mentioned in the docs for mongodsn?
