For several days I noticed that Salesforce and Marketo data is not syncronizing anymore.
For example, if I change the Lead Status in Salesforce it will not update the status in Marketo also and vice versa.
If a lead will be created in Salesforce it will not appear in Marketo.
Also when I try to syncronize campaigns from Marketo to salesforce I receive the error from the attached picture.
The weird part is that I don't have any Notifications with any mentions of the sync problems and I don't know how to identify the issues. Did anyone experience this issue before? What should I do to fix it? (or at leas identify the issue)?
