MEGA [https://mega.co.nz/] fails to load

Hi

It's very easy to reproduce. Make sure you have AdGuard protection enabled before starting web broser. MEGA https://mega.co.nz/ will fail to load with an error message:
"The file https://eu.static.mega.co.nz/html/start_3.html is corrupt"



Currently I don't know the fix either than just disable AdGuard before starting web browser then load the site and enable protection again.
The problem is nothing new, I think I had it on non-beta AdGuard versions. I always though MEGA has some problems.

Filters enabled: english, spyware, social-media, Adblock Polska
Browsing security: phishing, malware,

Workaround
Add exclusion for HTTPS filtering (in 5.10 Settings -> Network -> Exclusions:
Code:
eu.static.mega.co.nz
and restart browser

You can try disabling filters one-by-one until you find which filter list is causing this issue. :)

As I said in first post, the only one way to fix it is to disable Adguard and restart browser so it's not filter issue. If Adguard was enabled before starting browser then even disabling all filters, both security modules and all three extensions won't fix it. Disabling https filtering or/and adding mega.co.nz to exclusion list doesn't help.
MEGA is very complicated and secure site. Adguard affect on programs to filter theirs connections. MEGA may detect 'something unusual' like changes in Chrome process memory so it doesn't want to load at all.

Odd, loading up the main Mega URL works fine for me. Anyone else able to reproduce this?

Did you guys check it on Chrome? Are you sure you didn't have mega in browser cache? I run incognito mode at startup so it never uses cache.

Not about for long but i have used mega many times in the past without issue. I have just tested mega now with updated filters and it worked fine this is with chronium. I would downlad something but im currently hijacking someones wifi ;)

Please try adding this rule to your user filter:
Code:
@@||static.mega.co.nz^$document
Does it help?

Nope it doesn't. Also tried on Firefox:
An error occurred while loading MEGA. The file https://eu.static.mega.co.nz/html/bottom2_3.html is corrupt. Please try again later. We apologize for the inconvenience.
Maybe the site doesn't like code injection, I mean do some self-checks while loading and that's why it fails. Maybe the certificate causes this problem?

It's interesting if I'm the only one with this issue.

I reinstalled Windows lately. Had same issue before.

EDIT: Ok I think I got it. For testing I disabled https filtering and restarted Chrome. Then MEGA showed MEGA certificate and the site loaded correctly this time.

To solve it once and for all I added exclusion for HTTPS filtering:
Code:
eu.static.mega.co.nz
The site shows it uses AdGuard certificate and seems to be running fine.

It's still interesting nobody can reproduce it. I'm always running browsers in incognito/private etc...

Can you enable SSL от MEGA, close browsers and full exit from AdGuard, and move files from C:\ProgramData\Adguard\NetworkTemp\SSL to other folder? Then you can run AdGuard and browsers.

What @Alex302 was trying to say:

1. Stop Adguard (don't forget to stop Adguard Service along with UI)
2. Clean %programdata%\Adguard\NetworkTemp\SSL folder
3. Run Adguard again

There is a possibility that Adguard generates wrong certificate for MEGA.
Cleaning SSL folder will reset all certs generated by Adguard.

avatar@: Ok, so I deleted previously added exclusion for HTTPS filtering for eu.static.mega.co.nz​ and done everything like you said.
Nothing changed, still same errors.
However the exclusion seems to be working workaround ;)
