I have few sites. Example bittires.com.ua. Some clients can’t reach any of them.
I has access to one of this device for few hour per day, i checked everything i can imagine.
- on FireFox sites are working if in settings checked “DNS over HTTPS”, server - Cloudflare.
- Chrome - not working
- Edge - not working
- If use some proxy - Chrome working. After proxy off Chrome stil working some time 1-10 hour.
- [Checked] DNS resolve - right Ip address, same as on other devices
- [Checked] TCP monitor, Chrome is trying connecting to right IP address
- [Checked] nginx server log, no request reach server from this device when site not opening.
