I use the #Blokada#wireguard#VPN on 5 devices: 4 #Linux boxes and an Android phone. This morning, internet on two of the Linux boxes crapped out when connected to the VPN. TCP connections were taking ridiculously long or hanging completely. For example, I saw "time curl --silent https://cnn.com/" take over a minute with the VPN connected vs. a fraction of a second without. Disconnecting and reconnecting to the VPN didn't help. Neither did rebooting. (continued)
Eventually I found something that fixed it: I deleted the VPN config from those two boxes, deleted them from the Blokada app, added them back there, downloaded the new VPN configs from there, and imported them into the boxes. Everything worked fine after that (indeed, I'm posting this message through the now-working VPN connection). Has anybody else seen anything like this on Blokada in particular or wireguard in general? Any thoughts about potential causes? (continued)
