@MrHalfpint Sorry to hear that, its unfortunate that the .ovpn aettings i provided did not resolve ur situation. When you use your .ovpn in the client vpn of the router do you need to enter a password or is it without password. If it requires password it wud suggest the password line is encrypted.. the settings i sent you if you use exactly that settings as it is and then ur ca cert key and open in openvpn client. If it works then try in the router and it is connecting suggests the issue is inside ur ca cert or key.

Put all my settings as stated into a .txt followed by ur ca cert and key and ensure of course the ip is correct and udp.

Tey it on client and router if client connects and not router, issue is in one of ur 3 ( ca cert key )

  @SteiniPe I made a little progress.. I'll try adding passwords next..

  @MrHalfpint In my case I couldnt use password, that made it encrypted password,and stuck at connecting. So i generated my user wirh nopass which allowed immediate connected.. Either way your situation is slightly different but it seems to something in that .ovpn file that isnt working for that router, u cud generate a new file if its ur openvpn server with nopass, anyway hope u get it sorted otherwise scroll down and find the TP link support who is responsing here and ask to escalate to support like they did with mine. They can run ur ovpn file and know exactly what it is.. Ive asked them to consider adding more verbosity to router logs because we get no answers there.. lets hope they do.. sorry i cant help u any more than this :/

  @Kevin_Z 

Router:AXE5400

Trying to use as a vpn client and it is stuck on connecting.

ovpn file does not have encrypted key and starts with -----BEGIN PRIVATE KEY-----

Any help here?

  @SteiniPe I got this far by deleting the "allow-compression no" in the generated .ovpn.  I have a call into my VPN service.. (KeepSolid VPN)  No changes with or without passwords.

openssl pkey -in secure.key -out plain.key

I must add that I also initially tried with the actual key ( as in <key>......[...].....</key> ) and that also got stuck in connecting.

I also tried IPSec ans it al stays "connecting"... forever....

Please help! :)

  @danoffline Your  <Key> does it start with BEGIN PRIVATE KEY or BEGIN ENCRYPTED PRIVATE KEY

  @MrHalfpint Have you tried contacting the support, I know they want to "raise a ticket" sometimes but maybe you could reach out to them, Guy named Noah Wng (Get it, this forum doesnt allow me to spell his name with a "a" because its profanity ;D) sorted me through email support.forum@tp-link.com, im not sure if you are allowed to contact noah directly as I have his email from that ticket as he was CC'd, but if you reach out to them raise a ticket about this forum post, provide them with the details they may be able to help. Just make sure to include the "openVPN configuration file" without IP and Port, he can verify your options if they require fixing.

  @SteiniPe Thanks for all your time and help.  I have been in contact with Noah for more than a week and he is doing his best.  I've tried installing some beta firmware he sent but still can't get any better results.  

There are two (2) things that seem strange.

1)  I get the same results when I try to use L2TP/IPSsec protocol.

2) When I remove compression it will say connected but it's not and I get a ? saying server: null and dns:10.80.0.1

All of the generated .ovpn files work with the OPVNClient. 

I've sent log files from both the OPVNClient and TPLink (adding "log-append /tmp/smb/G/log.txt" will generate a log to the usb drive) file.
