Hi! In 1.7.9 with crt-base and ca-base in global haproxy try to search crt for server in ca-base. In bind all work as expected. If I specify the full path for crt in server - it's ok.
# cat /tmp/haproxy.cfg global ca-base /etc/haproxy/ca-base crt-base /etc/haproxy/crt-base defaults mode http timeout connect 5s timeout client 120s timeout server 120s frontend cs bind *:4000 ssl crt test_combo.pem ca-file cabundle.pem verify required default_backend cs backend cs server s1 1.2.3.4:4000 ssl crt test_combo.pem ca-file cabundle.pem verify required # haproxy -c -f /tmp/haproxy.cfg [ALERT] 324/193009 (30768) : config : backend 'cs', server 's1': unable to load SSL private key from PEM file '/etc/haproxy/ca-base/test_combo.pem'.
