Hi Everyone,

I have installed magento 2.3 fresh magento 2 version.

And then installed the sample data.

But when I login to admin panel, I am getting this issue:

 "A technical problem with the server created an error. Try again to continue what you were doing."

Hi @lokranjan_varshney

I would suggest you to go into var/log directory from the magento 2 root folder and then open the exception.log file and check what error it is showing over there and paste the error over here.

so its help us to troubleshoot the issue !

[lokranjan_varshney]

There is nothing error in var/log.

I also try to check the error_log server file but no success

Yes I see that but I only installed the fresh m2.3 and did nothing in the code.

I tried to find out what is wrong and why there is 404 error over night but could not succeed.

Hi @lokranjan_varshney,

I am also facing the same issue in Magento 2.3. Did you find any working solution for this issue? If so please help me to resolve this issue.

@prema_mani1

I did not get any solution for this issue.But when I used the same files and database on my local even without a single change.It works fine without any issue!!!!

I think the issue is related to server.I have checked the server error log and magento error log 

but there is no hint for this kind of error.
