Other Troubleshooting Tips
If content is not loading and you see a message about a proxy server, contact your IT service team to review the possible solutions below.
The problem is usually caused by a proxy / firewall that interrupts the communication between the content and authentication server.
Why proxy servers affect the process:
Proxy servers are designed to protect your organization from unwanted viruses, malware, and other phishing types of schemes. However, some types of communication are warranted, such as the content you're trying to access from a legitimate and trusted source.
Proxy server required configuration changes
The proxy must allow direct communication with the DNS address: www.astm.org
Firewall required configuration changes
Remove any blocks in Norton or other firewall software for docs.astm.org
