Trailhead Access - Firewall Issues
Trying to give users access to Trailhead , but Firewall blocking access. Is there a range of IP addresses that we should whitelist specifically for Trailhead? We have already whitelisted the recommended IP ranges for our Salesforce access and all is working fine. Not sure if we should whitelist a single IP or if there is a range. Thanks, Brent.
This isn't a total answer to your question but hopefully will add some value. I just checked and trailhead is being served to me from 104.16.3.19 which is not in the whitelist mentioned here => https://help.salesforce.com/apex/HTViewSolution?id=000003652.
If you are having issues is there any way you can just whitelist the domain name and not an ip or ip range?
