Invalid HTTP_HOST header

[discover59]

I used raven package in Django before and it worked well so far.
Recently I replaced it with latest sentry-python and getting weird error notifications continuously.

Invalid HTTP_HOST header: 'server_ip'. You may need to add 'server_ip' to ALLOWED_HOSTS.

I added server domain, 127.0.0.1 and localhost in allowed hosts.

I think there is no direct request to server IP instead of the domain.

Any help to fix the issue is appreciated.

Where are you getting that error? In your project or when submitting events from the SDK to Sentry?

[discover59]

Sentry is integrated in my django project and the same event from the project pushed to sentry.
Sometimes it also produces events with example.com and 169.254.169.254 instead of server_ip.

Could you link me the sentry issue that shows this error?

Yeah this came up a few times before. I think we should just start ignoring that logger, for now you can do:

from sentry.integrations.logging import ignore_logger
ignore_logger("django.security.DisallowedHost")

Thanks.
But I cannot ignore all errors related to DisallowedHost.
I have to track some of those.
Not sure why there are example.com and other strange server ips.

[untitaker]

Because those errors happen. Somebody is sending this as Host header. I am not sure by which criteria you want to filter.

[discover59]

Is it possible to ignore errors with certain host headers in project?
I don't want such invalid errors to fill my sentry event count.

[untitaker]

Yes, you can use the before_send option to look at the event that is about to be sent and return None to throw the event away. I would recommend print(event) in development to figure out which keys to look at for DisallowedHost.

[discover59]

Ok, let me try. Thanks.

Another option is to use the "message filters" option in the project settings.

I'm having the same Issue.

@untitaker if i choose the "message filters" it will count at the sentry messages per month?
