deskutils/nextcloudclient Cannot connect securely to

FreeBSD 12-STABLE from Oct 15
nextcloudclient 3.3.5

I get popup messages from the client stating "Untrusted Certificate 
Cannot connect securely to [server-name]".

Browser access to the server is fine, no errors.

Using truss, it seems it looks for and finds
fstatat(AT_FDCWD,"/etc/ssl/certs//2e5ac55d.0",{ mode=-r--r--r-- 
,inode=192371,size=4665,blksize=5120 },0x0) = 0 (0x0)
open("/etc/ssl/certs//2e5ac55d.0",O_RDONLY,0666) = 106535 (0x1a027)

But 2e5ac55d.0 (DST_Root_CA_X3.pem) has expired.

It also looks for 8d33f237.0, but it does not exist:
fstatat(AT_FDCWD,"/etc/ssl/certs//8d33f237.0",0x7fffdf5f70a0,0x0) ERR#2 
'No such file or directory'

How do I convince it to instead look for 4042bcee.0 which is the 
ISRG_Root_X1.pem used by Letsencrypt?

Thanks,
