AS6 certificate errors compared to AS4.12

Hi Community,

great explanation ( UAExpert, mappView: How to make a secure OPCUA connection to OPCUA server with communication partner validation - #12 ) - everything works for me when using AS4.12. However, trying to set this up in AS6 ends up in an error on UAExpert.

Also, i found out it works in AS6 when i use the certificate created in AS4.12, but never with the certificate created in AS6.

Any idea here?

Hi @Thomas.Haindl ,
We have customers that have created new certificate with AS 6 and no issue.
Could you please share with us the steps you did when you created the new certificate with AS 6?

==========================
In few cases with OPC UA connection issues we saw “BadSecurityChecksFailed”:

just to compare 1:1 all issues could you upload SystemDump too?

Thanks
Ciao

I found similar report and it was caused by outdated version of UAExpert client. Can you tell us what version do you have and maybe update client to the latest one?
