You're right, thanks. Removed it from the list completely.

@Manouchehri Thank you. I think the list should also not contain the following as they are not working anymore

• http://timestamp.globalsign.com/scripts/timstamp.dll
• http://timestamp.globalsign.com/?signature=sha2
• http://timestamp.wosign.com

You are correct. My team had already removed those from our rfc3161.ai.moda load balancer, but I forgot to update the list here too.

Add http://ts.ssl.com

http://ts.ssl.com

Is there link to certificate(s) that are used for the TimeStamp? We need to put them into trusted list.

Found here: https://www.ssl.com/how-to/install-ssl-com-ca-root-certificates/

@JohnPlanetary WOW thanks for that list, it really helped.
