Popravite da vaša veza nije sigurna Pogreška: ^{(Fix Your Connection is not Secure Error: )}Mozilla Firefox je široko korišteni web preglednik koji je jedan od najpouzdanijih web preglednika svih vremena. Mozilla Firefox provjerava valjanost certifikata web stranice^{(Mozilla Firefox verifies the validity of website certificates)} kako bi se uvjerio da korisnik pristupa sigurnoj web stranici. Također provjerava je li enkripcija web stranice dovoljno jaka kako bi se očuvala privatnost korisnika. Problem nastaje kada certifikat nije valjan ili enkripcija nije jaka i preglednik će početi prikazivati ​​pogrešku " Vaša veza nije sigurna^{(Your Connection is Not Secure)} ".

Problem može biti povezan s Firefoxom^(Firefox) u većini slučajeva, ali ponekad problem može biti i na korisničkom računalu. Ako se suočite s gornjom porukom o pogrešci, možete jednostavno kliknuti gumb " Vrati se^{(Go Back)} ", ali nećete moći pristupiti web stranici. Drugi način je da nastavite do web-mjesta tako da poništite upozorenje, ali to znači da izlažete svoje računalo riziku.

Zašto se suočavate s pogreškom "Vaša veza nije sigurna"?^{(Why you’re facing the “Your Connection is not Secure” error?)}

Pogreška Vaša veza nije sigurna^(Secure) obično je povezana s kodom pogreške SEC_ERROR_UNKNOWN_ISSUER  koji je povezan sa ^{(SEC_ERROR_UNKNOWN_ISSUER )}SSL -om ( Slojevi sigurnih utičnica^{(Secure Socket Layers)} ). SSL certifikat^{(SSL certificate)} se koristi na web stranici koja obrađuje osjetljive podatke kao što su podaci o kreditnoj kartici^{(Credit Card)} ili lozinke.

Kad god koristite bilo koju sigurnu web stranicu, vaš preglednik preuzima sigurnosne certifikate Secure Sockets Layer ( SSL ) s web-mjesta kako bi uspostavio sigurnu vezu, ali ponekad je preuzeti certifikat oštećen ili konfiguracija vašeg računala ne odgovara onoj SSL certifikata. Da biste ispravili ovu pogrešku, postoji nekoliko načina od kojih su neki od njih navedeni u nastavku.

Fix Your Connection is not Secure Error on Firefox

Fix Your Connection is not Secure Error: Mozilla Firefox is a widely used web browser which is one of the most trusted web browsers of all time. Mozilla Firefox verifies the validity of website certificates in order to make sure that the user is accessing a secure website. It also checks that the encryption of the website is strong enough so that the user privacy is maintained. A problem arises when the certificate is not valid or the encryption is not strong then the browser will start showing an error “Your Connection is Not Secure“.

The problem can be related to Firefox in most cases, but sometimes the issue can reside on the users PC as well. If you face the above error message then you can simply click the “Go Back” button but you won’t be able to access the website. Another way is to continue to the website by overriding the warning but that means you are putting your computer at risk.

Why you’re facing the “Your Connection is not Secure” error?

Your Connection is Not Secure error is usually associated with SEC_ERROR_UNKNOWN_ISSUER error code which is related to SSL (Secure Socket Layers). An SSL certificate is used on the website which processes sensitive information such as Credit Card information or Passwords.

Whenever you use any secure website, your browser downloads the Secure Sockets Layer (SSL) security certificates from the website in order to establish a secure connection but sometimes the downloaded certificate is corrupted or your PC configuration is not matching that of the SSL certificate. To fix this error there are a number of ways out of which some of them are listed below.

Simply disconnect the power plug of your device and reconnect after a few minutes in case you are using a combined router and modem. For a separate router and modem, turn off both the devices. Now start by turning on the modem first. Now plug in your router and wait for it to boot up completely. Check if you can access the Internet now.
