gzip is not working properly on Hummingbird

Well, having the same problem again. I would like to have it sold as is the second time that happen to me. If anyone have any experience with the warning message below I will apreciatte.
I diod check with the hosting company and they said that the deflate module is enabled.

gzip is not working properly:
- Your server may not have the "deflate" module enabled (mod_deflate for Apache, ngx_http_gzip_module for NGINX)
- Another plugin may be interfering with the configuration
If re-checking and restarting does not resolve, please check with your host or open a support ticket with us.

Thanks to anyone.
