Hello! We're glad to inform you that Hummingbird 1.0.2 has just been released. Hummingbird is a free and open source software by AirVPN for: Linux x86-64 Linux ARM 32 (example: Raspbian for Raspberry Pi) Linux ARM 64 macOS (Mojave or higher version required) based on OpenVPN3-AirVPN 3.6.3 library supporting CHACHA20-POLY1305 cipher on OpenVPN Data Channel and Control Channel. Hummingbird is very fast and has a tiny RAM footprint. AES-CBC and AES-GCM are supported as well. Version 1.0.2 uses new OpenVPN3-AirVPN 3.6.3 library. Important: if you build Hummingbird please make sure to align to AirVPN library 3.6.3. You can't build Hummigbird 1.0.2 with library versions older than 3.6.3. Hummingbird is not aimed to Android but you can have CHACHA20-POLY1305 on Android too: please run our software Eddie Android edition, which uses our OpenVPN3-AirVPN library. TCP queue limit If you connect over TCP, Hummingbird will set by default a minimum TCP outgoing queue size of 512 packets to avoid TCP_OVERFLOW errors. If you need a larger queue in TCP, the following option is now available from command line, in addition to profile directive tcp-queue-limit: --tcp-queue-limit n where n is the amount of packets. Legal range is 1-65535. We strongly recommend you to allow at least 512 packets as queue limit (default value). Larger queues are necessary when you connect in TCP and need a lot of open connections with sustained (continuous) but not necessarily high throughput, for example if you run a BitTorrent software. In such cases you can enlarge the queue as much as you need, until you stop getting TCP_OVERFLOW. It's not uncommon from our community as well as our internal tests to set 4000 packets queue limit to prevent any TCP overflow. If you connect over UDP, you can ignore all of the above. Network Lock Network Lock prevents traffic leaks outside the VPN tunnel through firewall rules. Hummingbird 1.0.2 widens --network-lock option arguments. The following arguments are now accepted: on | off | iptables | nftables | pf (default: on). If you specify on argument, or you omit --network-lock option, Hummingbird will automatically detect and use the infrastructure available on your system. Hummingbird picks the first available infrastructure between iptables-legacy, iptables, nftables and pf. Note: command line options, when specified, override profile directives, when options and profile directives have the same purpose.

At least once a day I get the "our tubes are clogged" message. No other website I visit is as unreliable as this one. When it is down I can't get to my client area to configure my VPN. So, it is important that the website is working. What's more, no other web site I frequent is as slow to respond as this one as I browse through the forum. I can literally check on other forums in the time I'm waiting for this site to respond. All this is while using AirVPN VPN servers. Thanks for your attention.

I can confirm this. The website has some flow-breaking bugs which affect reliability. Sometimes this message appears after writing long post texts, rarely quite suddenly when moving to first unread posts. The funny part is: If I remove the comment thing in the URL, it loads normally. One user also experienced it when he/she wanted to download a generated profile but Safari instead downloaded the error HTML page. Then that user asked in the forums why he/she couldn't import the profile.
