help with openvpn server, configured on dd-wrt router, remote (internet) access from iphone client

looking for help...i am seeking someone knowledgeable, skilled as well as experienced with the following solutions; openvpn server (via feature of dd-wrt router firmware), openvpn client (installed onto iphone), and dd-wrt router firmware in particular too. i want to VPN from iphone/cellular internet service, into my recently configured home router (dd-wrt) using openvpn client on iphone and the openvpn server on dd-wrt router. i am trying to access my homes internal resources from the internet from vpn (vs firewall port forwarding to servers directly), something more securely and safely like vpn, using encryption, tunnels, etc. i have already downloaded openvpn onto windows host, created some certificates and keys to be used on server and client systems, already installed them into dd-wrt router and iphone via *.ovpn files (along with certs/keys) and so far, it appears i have successfully setup dd-wrt openvpn server, because its status is "connected; success" under state tab in dd-wrt. the dd-wrt router/openvpn server is actually logging connection "attempts" from iphone openvpn client already, too. so iphone to dd-wrt router connectivity already exists. iphone is reaching dd-wrt router and attempting to establish the vpn - but is not working, and appears to be failing at this time. this is what i need help to correct...get the connection established, successfully, then get the iphone access to internal resources, like internal web cam server and others too. if you require more info or want to know what specifically is happening at this time....here that information is now; ***the iphone error is simply stating; connection timeout ***dd-wrt router, openvpn server logs are as follows; 20171222 12:39:03 N IPHONEIPHERE:6713 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity) 20171222 12:39:03 N IPHONEIPHERE:6713 TLS Error: TLS handshake failed 20171222 12:39:03 IPHONEIPHERE:6713 SIGUSR1[soft tls-error] received client-instance restarting 20171222 12:40:15 IPHONEIPHERE:6714 TLS: Initial packet from [AF_INET]IPHONEIPHERE:6714 sid=3625ba21 a18d70e0 20171222 12:40:26 N IPHONEIPHERE:6714 VERIFY ERROR: depth=1 error=certificate is not yet valid: C=US ST=STATE L=CITY O=OpenVPN OU=OUNAME CN=CNNAME name=NAME emailAddress=EMAIL@[login to view URL] 20171222 12:40:26 N IPHONEIPHERE:6714 TLS_ERROR: BIO read tls_read_plaintext error: error:140890B2:lib(20):func(137):reason(178) 20171222 12:40:26 N IPHONEIPHERE:6714 TLS Error: TLS object -> incoming plaintext read error 20171222 12:40:26 IPHONEIPHERE:6714 NOTE: --mute triggered... 20171222 12:40:26 IPHONEIPHERE:6714 1 variation(s) on previous 3 message(s) suppressed by --mute 20171222 12:40:26 IPHONEIPHERE:6714 SIGUSR1[soft tls-error] received client-instance restarting 20171222 12:41:08 IPHONEIPHERE:6691 TLS: Initial packet from [AF_INET]IPHONEIPHERE:6691 sid=fac9c20a 13a11608 20171222 12:41:18 MANAGEMENT: Client connected from [AF_INET][login to view URL] 20171222 12:41:18 D MANAGEMENT: CMD 'state' 20171222 12:41:18 MANAGEMENT: Client disconnected 20171222 12:41:18 MANAGEMENT: Client connected from [AF_INET][login to view URL] 20171222 12:41:18 D MANAGEMENT: CMD 'state' 20171222 12:41:18 MANAGEMENT: Client disconnected 20171222 12:41:18 MANAGEMENT: Client connected from [AF_INET][login to view URL] 20171222 12:41:18 D MANAGEMENT: CMD 'state' 20171222 12:41:18 MANAGEMENT: Client disconnected 20171222 12:41:18 MANAGEMENT: Client connected from [AF_INET][login to view URL] 20171222 12:41:18 D MANAGEMENT: CMD 'status 2' 20171222 12:41:18 MANAGEMENT: Client disconnected 20171222 12:41:18 MANAGEMENT: Client connected from [AF_INET][login to view URL] 20171222 12:41:18 D MANAGEMENT: CMD 'log 500' 19700101 00:00:00 Clientlog
