Hi @Rajkumar181
As you can see in the log:
Last error was: -10368 - X509 - Allocation of memory failed
This means you ran our of memory when parsing the server certificate.
However, we have been working on a feature to reduce RAM usage in X509 certificate parsing, however it hasn’t been released in an official version yet.
You are welcome to use latest development version, nd test this feature, if you wish.
