Hi,
I'm troubleshooting an issue for a client of mine who has issues connecting to documentcloud.adobe.com / acrobat.adobe.com, but after the original TCP negotiation, TLS connection fails.
We've moved the client over to another ISP with another IP temporally and the site is accessable again.
Is there a way for me to check if Adobe might be blocking their IPs?
Kind regards,
Neil van der Merwe
Hi @neil_2774,
Thank you for reaching out. As mentioned, you are encountering connectivity issues with one ISP, where the TLS connection fails; however, switching to another ISP with a different IP successfully resolves the issue. Here are some steps you can follow to resolve the connectivity issue:
Firewall Rules: Ensure that no outbound or inbound traffic is being restricted by the local network’s firewall or the ISP’s firewall, particularly for ports required by TLS (typically port 443).
Adobe Service Check Tool: Adobe provides a diagnostic tool that can help identify connectivity issues. This tool checks the accessibility of Adobe services from your network. You can access it here.
Network Configuration: Ensure that all necessary URLs and endpoints required for Adobe services are allowed through your network's firewall. For a complete list of URLs and IP ranges, please refer to the following document: Allowlist URLs for Adobe Services.
Additional Resources: If you are experiencing connection errors or general connectivity issues with Adobe applications, the following resources may also be helpful:

Please let me know if you have any additional questions.
