@myall200 How you got this error? Missing details, if you are with Ocelot please let us know.

This issue can be directly closed @raman-m, cause details are missing. For me LB is working fine in my test case.

[raman-m]

@ks1990cn @ggnaegi Isn't this bug reproducible?
The bug issue is pretty fresh: of previous year reporting... But Yes, the author should provide more details on the bug...

Hello zenghao!
Welcome to Ocelot world!
Could you attach logs, routes config.json and more plz?

[ks1990cn]

@myall200 Are you with Ocelot anymore. @raman-m we can close this now I think. If anyone else comes with similar problem and discriptions we can take a look going ahead!

[raman-m]

@ks1990cn I will close with pleasure in a month if the author doesn't care about own issue.
Let him (her) have some time to return to us back...

This contributor doesn't care even about current open PR #1372 ... (S)he is just silent... 😢

[raman-m]

@myall200 Dear zenghao,
Sorry for being late in responding to you in 2022...

You have one month to react, to write us back till January 5, 2024...

Otherwise your issue will not be accepted and closed.

[raman-m]

No communication with the author!
