Problem while mounting container

[Alex Bunet]

I have an encrypted Veracrypt container
Within a month I mounted it without any problems, but today I can not mount it - the error is "wrong password", but I am sure that the password is correct.
I tried restoring the headers from the volume, but it didn't work. I have no other copy of the titles.
How do you know exactly what the problem is in the headers?
How can you solve my problem?

I'm not a specialist, but somehow your problem might be related to these two topics:

1.) Which OS and which VC versions do you have currently installed on your computer?

2.) Please, check the following option to try to mount your VC volume again:
'TrueCrypt Mode' ENABLED => VeraCrypt Volume didn't mount! (Screenshot_21_1.png)
'TrueCrypt Mode' DISABLED => VeraCrypt Volume did mount! (Screenshot_22.png)
