No Common Encryption Algorithm


We’re using XML-RPC API calls to different Infusionsoft accounts. Oddly, only for one of them, this CURL error message started to be returned all the time:
“Cannot communicate securely with peer: no common encryption algorithm(s).”

Were there any recent updates to the API calls requirements?
Why would this issue influence one account requests only?


Hey! We did update our system to require TLS 1.2 I would check to see if you are using an older version and update it.

yes, adding -TLSv1.1 to already disabled v1.0 -TLSv1 fixed this issue.

Hm, some time has passed. The same error is still logged occasionally, ~twice per day (roughly less than 1% of all the requests), for different accounts.
Any idea what may go wrong?
