SFDC sync errors "SSL read: errno -5961"

[Amanda_Sanchez2]

Marketo is trying to make a handshake to the SFDC Server and the SSL Handshake is failing every day.

I am getting the below error message daily, and I'm having a hard time getting SFDC support to even investigate the error message unless I pay for the Premium support tier. Has anyone successfully resolved this? I am using the out-of-box Marketo-SFDC integration.

Salesforce Sync Error

This problem should be automatically resolved

Why: Marketo/Salesforce sync is unable to connect to the Salesforce instance.

Error details: Marketo encountered the error "SSL read: errno -5961" when attempting to connect to Salesforce.

What to do now?

This may be a transient issue. If you are frequently seeing this error, contact Salesforce support.

We are getting the same error every day or two. No direction from Marketo Support and SF admins are at a loss. Seems like a common issue among customers. Has anyone actually found any records not syncing because of it?

been keeping an eye very closely on this and thankfully have not seen any sync issues YET.  Either way, they really need to get this fixed.

HI guys,

So i got this update from support.  Not sure im totally convinced this isnt a problem and its not possibly causing flow step errors (such as "sync to salesforce") but who knows...the answer is very vague.

"This is a transient error that occurs when Marketo is (temporarily) unable to connect to Salesforce.  When this occurs an error notification is generated but no action is needed. We have error handling on our end that prevents this from impacting the sync."

Their engineering team also examined the frequency of this error and stated that it does not appear to be happening frequently (I have pushed back on this as it is a daily occurrence in my instance.)

Their conclusion is that we should ignore this error as its not impacting anything.  The have confirmed that the error is sitting on the Marketo side of the house so my SFDC support team closed their case.

Anyway...to me it doesn’t sound like they are prioritizing this as there is no direct impact to data.

Has anyone heard back from Marketo on this yet? We've been getting this same error, first intermittenly, now daily for the last week.

Any resolution we have for the following errors?

Marketo encountered the error "SSL read: errno -5961" when attempting to connect to Salesforce.

Also have been getting this error for weeks and cannt get a definative root cause  from Marketo or SFDC support.  Attempting to get both on the phone together.  Will report back any findings that I come across.

Any solution / ideas / recommendations about this error?

We've been getting the same error for the past few months as well. We're in the middle of a major release to migrate rest of the company to SF, so we have not had time to troubleshoot the error. Interested in hearing what the resolution is.

What is the canonical SFDC URL for your org?

Sanford Whiteman sir, could it be a throttling issue?

[SanfordWhiteman]

Looks to be a low-level networking issue. You should concentrate on the Marketo side first because na73 isn't doing anything special that I can see.
