If you are using a Mikrotik router, reset it to factory settings and upgrade the firmware to the latest version.

If that doesn't help, it could be that your ISP is using a compromised Mikrotik router.

Thanks for your reply,

I don't understand why Mikrotik can be the issue here. Can you please explain it to me.

Also when i try to open the same link from my Laptop its OK, but from the Server i am getting this report. If it was something to do with the Mikrotik why from my laptop it works.

To begin with, the issue is not solely related to Mikrotik. Other router manufacturers have also been identified as having vulnerabilities.

Also, the issue is not restricted to locally installed routers. Many ISP routers and related backbone devices have been likewise infected. Many of these like recent postings in the forum have been traced backed to the ISP equipment being the source of the infection.
