Vivaldi unusable with constant checking if connection is secure

MalcolmCZ

Hello, for a few days now I have a problem with constant connection checking whenever I open any new website. Official vivaldi website won´t even let me to the page with constant are you a human checks. Some pages won´t load pictures or video. This makes browser completely unusable and to write this I had to use different web browser to be even let on this page. Is there any fix for this? Thank you for any help/advice.

Example from eshop:

@MalcolmCZ Welcome in our Vivaldi Community

Enjoy browsing with Vivaldi.

Some useful links for you:

DoctorG

@MalcolmCZ I guess you use VPN/Proxy or some "privacy" extension which changes user-agent.

MalcolmCZ

@DoctorG I´m not using any VPN, only extension I have is ADblock plus, which I was using ever since when starded using vivaldi (2+years) without any problem.

DoctorG

@MalcolmCZ Any security tool or older OS?

MalcolmCZ

@DoctorG I´m using Windows 10 with latest update, for security I´m using free version of Avast.

Avast free antivirus is known causing issues.
But i can not tell you how to solve, i do not use it.

MalcolmCZ

@DoctorG I´ll try uninstalling it, but i haven´t had any issue with it so far and free version shouldn´t have any specific web tools like vpn. The problem is recent (2 days).

DoctorG

@MalcolmCZ Just try this before uninstalling: check Troubleshooting issues.

MalcolmCZ

@DoctorG I tried going step by step with troubleshooting issues you mentioned. Didn´t work. I didn´t see any change. Same with uninstalling Avast.

DoctorG

@MalcolmCZ I never saw such issue like yours with vivaldi.com, and i used 5.7.2887.3 and 5.6.2867.50 on Windows 11 22H2 for a test.

What happens if you check with a test profile (=close tab after Welcome page appears, d not male settinsg or add extensions)?

MalcolmCZ

@DoctorG I´ve made a profile, didn´t change anything and page "https://vivaldi.com/newfeatures?hl=cs&version=5.6.2867.50&os=W" that opened automaticaly on next card didn´t let me access that page. Still stuck with verify that you are human check.

DoctorG

@MalcolmCZ Could be that someone with your ISP connection and/or IP often drove attacks towards vivaldi.com servers.

Are you on a company/organisations/school network?

Try to restart DSL modem or restart router to get a new IP.

MalcolmCZ

@DoctorG Well everything is possible I guess. I´m not on any company/organisations/school network just on desktop on home network. Did that, got a new address, still no change.

DoctorG

@MalcolmCZ I try to ask internally, but pelase have patience, most of the team is on winter holidays and out of office at this time.

@MalcolmCZ

Hi,
Have you modified any Flag?

Try with the Snapshot and do a USB / Standalone install.

MalcolmCZ

@DoctorG Yes, thank you for your time.
@Zalex108 Hi, I don´t remember ever modifiing any flag. Just did the standalone install and same thing as with regular version. Only thing changing is the captcha button for a checkmark one.

Zalex108

Would somehow changed any network setting?

DNS
HostFile

Firewall

In case you can,
Try with Mobile HotSpot, just to test.

Also from system Events
Win+R - CompMgmt.msc

MalcolmCZ

@Zalex108 I didn´ t change anything before or after it started happening. Tried Mobile hotspot and it worked fine on both desktop and laptop.

Then it is causes by your modem/DSL Internet access provider or their router/modem filter/firmware.
