I have only seen this when I try to access mailwizz front or backend, also any links inside email that I send. No other sites I've seen. Also only when I'm on my at&t network. However if I use my phone as a hotspot for my laptop it works fine.Hello Yousef,
Sometimes it happen mobile network is continuously changing their dynamic IP and reset Internet connection in background. So may be due to that your Mailwizz session may end.
Can you check that you face issue this only in Mailwizz or any other websites same issue ?
Thanks,
VPul.
