gracefully handle TCP reset.

Hello, I was monitoring my Bitaxe BM1397, V2.0.7 and I got the error below:

After few moments the board rebooted normally and goes back to work. But it´s happening often. Almost every hour. I have a good power source (5A capable) as we can see at the picture:

I am using my board with Antpool. (ss.antpool.com:3333)

The problem does not happens when I use Public Pool. (public-pool.io:21496)

Had something similar

I realized that the ESP32 reboots every time it looses wi-fi connection.

Perhaps inelegant, but definitely effective.

[skot]

this seems related to #102 and could definitely use some attention!

[CoanLuciano]

I have been debugging this question using my router tools. I have a Mikrotik AP providing wi-fi to my bitaxe. I´ve been receiving this message every time bitaxe goes down:

84:FC:E6:6C:90:E8@wlan1: disconnected, received disassoc: sending station leaving (8), signal strength -30 In bitaxe I get the info posted above.

Bitaxe is pretty close to my AP. 2 meters away. Signal strength varies (-20 to -40).

[CoanLuciano]

I realized that the problem occurs when the pool server disconnects. I was tcpdumping and I got a TCP RST from antpool server, then bitaxe rebooted!

[skot]

Wow! Good catch. Maybe Antpool is suggesting you use a better pool 😂

We should more gracefully handle TCP reset.
