## Expected Behavior
Regular location should be updated.

## Actual Behavior
Regular location tracking is not working on some devices

## Steps to Reproduce
Just run the app with these configurations 

## Context
To get regular location updates

For problems with certain Android devices, see https://dontkillmyapp.com

[chirag-chopra]

I have already checked and your example application downloaded from play store is working fine. There is something issue with code. Please check our log file. As we are also getting

Failed to validate the certificate chain, error: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

[christocracy]

Failed to validate the certificate chain, error: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

Don’t use a “self-signed” certificate.

[adn9990]

in Server side APIs? @christocracy

[christocracy]

Yes. If your server is using a "self-signed" certificate, you cannot use an https url. You must use http.

[adn9990]

ohk, and have you checked vivo not working.txt log file. Why locations are not working on that device, is there any issue like this on vivo device or any other setup or configuration we need to do. Because example app downloaded from play store and checked on your server is working fine..

[christocracy]

There is nothing unusual in your Vivo logs. See https://dontkillmyapp.com

Then go outside and move > 1km.

[adn9990]

already checked with the same, all the four devices are together

[chirag-chopra]

we have checked ssl certificate, our server is using lets encrypt and we are able to make all network calls, Our certificate and we have also implemented more then 20 api alls are working fine. Expect your background location in some devices @christocracy

[github-actions[bot]]

This issue is stale because it has been open for 30 days with no activity.

[adn9990]

We are still facing this issue, @christocracy please reply

[adn9990]

Response: 0, java.security.cert.CertPathValidatorException: Trust anchor for certification path not found. Even others http request are working fine

[christocracy]

This plugin uses OkHttp for its http client.

[adn9990]

is there any solution available? @christocracy

[christocracy]

Is there anything in that thread which seems interesting to you?

I’m not hearing about this problem from anyone else.

[carmaa]

Any chance of introducing a Config property that would disable SSL/TLS certificate checking, say for enabling testing in dev environments that are using self-signed certs?

[christocracy]

I don’t know. Does OkHttp allow it?

[carmaa]

I don’t know. Does OkHttp allow it?

Don't know. But on second thought I'm just trusting the self-signed certs explicitly on my dev machine/device.

[github-actions[bot]]

This issue was closed because it has been inactive for 14 days since being marked as stale.
