dnspython exception

[lianke123321]

Saw this exception why running vpn.py:

Exception in thread Thread-1432:

@rpanah can u look into this?

[rpanah]

@lianke123321 do you have steps to reproduce?

[lianke123321]

@rpanah I was running top-500 baseline experiment while connecting to a purevpn endpoint.

@JASONews could you help look into this? Since you wrote dnslib unit test right?

[rpanah]

@lianke123321, do you know if this was addressed at any point in time?

[lianke123321]

@rpanah no, since it's still open.

[rpanah]

@lianke123321 I haven't seen this in the RPi nodes' log files. Did you encounter this with the VPNs again?

[lianke123321]

@rpanah I saw this in VPN walker's logs, you might want to check those logs.
