Playstation Network logon troubles

yujitfd

Greetings.

Windows 10, Vivaldi 3.4.2066.99 (Stable channel) (x64)

Wasn't able to log in to the Playstation account (https://store.playstation.com), website reports following:

A connection to the server could not be established.
(18.9ffd733e.1605041827.8de8af)

At the same time Chrome 86.0.4240.193 (x64) works fine, no adblock software was active during testing.
A couple of days ago I had no problem logging into PSN and making a purchase, only started today.
Also have to mention, that lately Vivaldi started working slower, more unreliable, regardless of disabled extentions. I cleared cache/cookies/etc completely - it didn't help either, it's becoming really annoying, so what else can I try?

Thank you in advance.

Hi, you can try with a guest profile https://help.vivaldi.com/article/guest-view/
to make sure no setting, extension or broken profile is the issue.
I have no account to test it but may other user can step by.

Cheers, mib
EDIT: Sometimes deactivate an extension is not enough, you have to remove it to be sure.

@yujitfd You need to accept 3rd-party cookies from [*.]sony.com and [*.]sonyentertainmentnetwork.com for the login to work properly.

Make sure you're not blocking 3rd-party cookies under Settings > Privacy > Cookies, and that you're not running any extensions that do so.

If you want to whitelist just these domains, you can add them to the accepted list through the Site Info (padlock) icon, then Cookies > Blocked and click Allow for the domains.

Thank you kindly for suggestions, I will tune V up as advised, but today I have news of my own

@mib2berlin yep, did try Guest as well, but still experienced same troubles.
@Pathduck, I do not block any cookie in Vivaldi on purpose, also having such websites whitelisted in adblock software (using AdGuard).

Still, today I was able to login successfully, and support request @ apple.com was also processed correctly despite giving me troubles a couple weeks back (never tested apple.com inbetween). Issue can be marked as self-solved, but still, I notice Vivaldi falling behind recently, as stated above, and I would not bother anyone if Chrome wouldn't works flawlessly a the same time.

@yujitfd Good
And what was the solution?
