It's only a comment, but, this message comes from NUT program netssl.c

 		status = NSS_NoDB_Init(NULL);
 	if (status != SECSuccess) {
 		upslogx(LOG_ERR, "Can not initialize SSL context");
 		nss_error("upscli_init / NSS_[NoDB]_Init");
 		return;
 	}

which does not call PR_GetError to retrieve the error code when NSS_NoDB_Init 
fails.  To find out more, you could add the PR_GetError call, complete the error
message, recompile, re-install and try again.

[Nut-upsuser] upsmon Can not initialize SSL context (letsencrypt) #563

Hello all.

Thx for the log-tip.

It was a access right violation on /etc.../letsencrypt/....cert . The folder was
own by root:root

Had to create a group nutusers including root and my nut users. After that, had
to change the chmod for the folder from 755 to 775

Now, running upsc -l

Init SSL without certificate database
850PRO

Witch is better. But still problématic wuth the init ssl database warning.
