Hi, we do have web filter but it isnt that as it works on an ssl vpn, just not an ipsec one, also after version 6.0.2 it doesnt work with an ipsec vpn and the web filter settings are the same throughout the versions.   Thanks for your input though :)   Regards

Hi, we have the same issue, it works on version 6.0.2.0128 and lower but any version above that and the calls wont work like you say.   I also cant believe this issue has existed for so long seeing as version 6.0.3.0155 and above have been out since 18th October 2018, and its not been fixed on any release after this...….

Hi, what firmware version are you running on your fortigate? we have a 1000c and are on 5.6.10 buiuld1677 (GA) and that is the highest version we can go up to.   I have tested multiple versions and the error first appears in version 6.0.3.0155 as when using version 6.0.2.0128 it works, we are going to log a support call with forti regarding this major issue.
