Connection error bbuseruploads.s3.amazonaws.com

[Deleted user]

Hi,

We are using bitbucket pipeline and a customer get connection error when trying to reach bbuseruploads.s3.amazonaws.com. I think customer needs to open specific ip addresses for this.

Where can I find which ip addresses that should be open?

I have looked in this guide https://support.atlassian.com/bitbucket-cloud/docs/what-are-the-bitbucket-cloud-ip-addresses-i-should-use-to-configure-my-corporate-firewall/ but could not find anything.

Please help me out.

Regards

Alexander

Hi Alexander,

In the documentation you linked in your post, there is a section titled "Valid IP addresses for Bitbucket Pipelines build environments", here:

• https://support.atlassian.com/bitbucket-cloud/docs/what-are-the-bitbucket-cloud-ip-addresses-i-should-use-to-configure-my-corporate-firewall/#Valid-IP-addresses-for-Bitbucket-Pipelines-build-environments

This section lists the IPs that need to be whitelisted for requests made from your build environments.

Please feel free to let me know if you have any questions.

Kind regards,
Theodora

I faced with the same situation when I tried to download Python Launcher, and I found that I can only connect to https://bbuseruploads.s3.amazonaws.com/  by using VPN.

Don't know why but it is blocked by some internet providers.

So, try to use VPN... :)

I had similar problems. I found out that our DNS resolver Quad9 was blocking bbuseruploads.s3.amazonaws.com 

We had to put a special rule to whitelist this domain on our own DNS server. 

Hope this helps someone. 

You can use this link to check if Quad9 is blocking it. Quad9 does update its list constantly.
