Hi,

I'm fairly new to OpenWrt and I'm getting the following error when trying to use OpenSSL in Python.

Any help or guidance you can provide would be greatly appreciated.

UPDATE: I've also encountered a very similar issue when running node.

Seems like there is a deeper SSL issue - any help would be much appreciated.

Solved - library mismatch.

Upgrading libopenssl fixed the issue.
opkg upgrade libopenssl

This pointed me in the direction.... https://bugs.openwrt.org/index.php?do=details&task_id=1205
