connect error: buffer_full : allocated=1 size=0 offset=512 capacity=3088 newcap=7696 #143

I could connect openvpn by test cli.cpp in Project ovpncli. But every time I connect successfully, it will be disconnect in 10 seconds. I notice the error message "buffer_full" and I don'y know if I should change some setting. Before I debug the cli.cpp I firstly install wintun driver and successfully install a new wintun driver tunnel. I also could connect ovpn by "dev tun" in my profile. Is there any methods to stay the connection? Thank you in advance.

Here is the log from command line:

I also try it in client and this issue will also appear. I found everytime I refresh some page in browser, the connection will be disconnected in signaling tun destroy event and the error is also "buffer error". Here is my profile setting context:

dev tun proto tcp remote 219.100.37.92 443 ;http-proxy-retry ;http-proxy [proxy server] [proxy port] cipher AES-128-CBC auth SHA1 resolv-retry infinite nobind persist-key persist-tun client verb 3

Should I change or add some setting in the ovpn file?
