SSL3 alert read: fatal: decrypt error

I have a ftpes connection that has been working fine using WinSCP but now i've getting the below connection error. It still works fine on Filezilla and worked yesterday on WinSCP (successful connection log at the bottom) but today it has stopped with the below errors. I have upgraded to the latest WinSCP 5.17.6 to rule out any issues.

Re: SSL3 alert read: fatal: decrypt error

Can you post a verbose FileZilla log file for comparison?
