UPDATE on this. I Change my "Device" key ( i used a different wireguard private public key on my nuc ) and IT WORKED !! wth?

Hi, I have installed ubuntu server 20.04 on a new Intel Nuc. My issue is that with Wireguard connected on my nuc, I cannot get to install from pipx command (and potentially others, I don't know how to check) nuc@usss:~$ pipx install --force pycowsay Installing to existing directory '/home/nuc/.local/pipx/venvs/pycowsay' WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ReadTimeoutError("HTTPSConnectionPool(host='pypi.org', port=443): Read timed out. (read timeout=15)")': /simple/pip/ ^CERROR: Operation cancelled by user It works with wireguard off ( sudo wg-quick down vpn and then pipx install pycowsay ) Another thing to note, is the with wireguard on, I can install from pipx command on another laptop with same vpn exit point. (but different keys). Any advice how to find out the root of this issue? I am not sure where to start. sysctl.conf as follows on new NUC (some rtorrent tuning and bbr mode) net.ipv6.conf.all.disable_ipv6=1 net.ipv6.conf.default.disable_ipv6=1 net.ipv6.conf.lo.disable_ipv6=1 ## net.ipv4.ip_forward = 1 ## disabled now, coz using nuc is a client #### some new valus ### # Maximum Socket Receive Buffer. 16MB per socket - which sounds like a lot, but will virtually never consume that much.

At the bottom of this file, add the following two lines: net.core.default_qdisc=fq net.ipv4.tcp_congestion_control=bbr routing works fine - https://i.ibb.co/270nTnx/image.png

https://ibb.co/XWHS8NH Turns out there is a setting on my router for "some" devices. I turned it on, and my connections seem to stay stabilize my connection. "Always Broadcast DHCP Server" I also added my laptops LAN addresses in QoS setting, to give it a higher priority.

How to view these logs? where are they located? (ubuntu 20.04)

HI, I am experiencing Frequent disconnection and reconnection, after my isp installed a new router. I suspect it's because of my ISP dns. (I have not changed it to cloudflare or quad9 yet which I had before). Could this be issue? It's on both of my ubuntu servers (2 old Laptops one connected via ethernet, another is via wifi ). They worked perfectly, and were connected for weeks. Is there any way to drill down where the disconnection occurs? Is it on my server end? my router? or airvpn end? I also have ipv6 disabled and some other settings -- # Some network settings net.ipv4.tcp_fin_timeout = 20 net.ipv4.tcp_slow_start_after_idle = 0 net.ipv4.tcp_tw_reuse = 1 net.ipv4.tcp_fastopen=3 net.ipv4.tcp_congestion_control=bbr ##### net.core.rmem_max = 16777216 # Maximum Socket Send Buffer. 16MB per socket - which sounds like a lot, but will virtually never consume that much.

IS there away I can allow to a connection between 2 devices (they are on same LAN) and both connected to same exit IP? What about a third one, not on same LAN...? Any advice on this?

It worked before and today itself I did ssh from one device to another device via LAN ip itself ( ``` ssh username@10.xx.xx.xx.xx ```)

Hi, This problem is confusing, I Dont know how to diagnose this. I have a https://domain.com:2222 and https://domain.com:3333 forwarded to internal SSL port ( 2222 and 3333 ) with A name on one of the Latvia Exit IP address. Same with ssh ports access ( domain.com:2223 ) ( domain.com:3334 ) I Cannot connect to these with my Latvia exit IP. ( Another netherland exit point also does not work ). SSH access also does not work. I CAN Connect without my VPN . And I used to connect before today with my vpn on This issue is going for few hours. PLEASE advice Devices show connected under my client sessions, and fail2ban-client shows nothing banned Edit I got to work, if I use another IP exit point. But why not same IP address?

Doesnt work with Netherlands servers. It works on some (or one) Singapore server. IDR which one.

Azire is good, but no open port, so I came here. All Round it's a good VPN. I did not use any media services, (netflix, prime etc) so I have no comment on that

https://i.ibb.co/2vyhhb4/image.png hello, Can someone advice me how to show a domain here, instead of airvpn ip. I have a domain.com on cloudflare. Any advice appreciated. (rutorrent window)

Thank you for your reply. Although I am not sure this is correct, as this will delete all my previous rules. Please correct me if I am wrong. iptables --flush 

Hello everyone, Can someone advice me the iptable or PreUP postdown rules to set up for Wireguard, if the airvpn server goes down (for maintenance or error). on ubuntu 20. Currently it's just this [Interface] Address = 10xxxxxxxxxxxxxxxxxxxxxxxxx6852/48 PrivateKey = oKdZxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx3ES1s= DNS = 10.128.0.1, fd7d:76ee:e68f:a993::1 [Peer] PublicKey = PyLCxxxxxxxxxxxxxxxxxxxxxxxxxxxxxuig+hk= PresharedKey = q0xxxxxxxxxxxxxxxxxxxxxxxx9BacQ= Endpoint = 134.19.179.146:1637 AllowedIPs = 0.0.0.0/0, ::/0 PersistentKeepalive = 15
