Website return blank page when generating all SSRS reports

Question

Recently, the database and SSRS reports were cloned to another server.
There was no change in VB.NET website except the config. connecting to database and report server.

Once the configuration is set, the configuration and settings kept unchanged.
Application Pool was restarted.
Sometimes the website return a blank page without error. But sometimes the reports can be generated successfully.

3 people (A, B, C) use different workstations:
First day, A (me) receive blank page (only A tried)

Second day, B can receive reports.
Then, A tried to generate reports and can receive reports

Third day, C receive blank page
A receive blank page
B can receive reports

The parameters should be correct because I used the same searching criteria.
Also, this happens to all the SSRS reports.

Answer 1

Hi @heiw123 ,
Are these two servers used at the same time? Try to change one of them to another TCP port.
Are there any error messages during this period? You could view 2017 and later versions in the following path: C:\Program Files\Microsoft SQL Server Reporting Services\SSRS\LogFiles
Could you share the error log corresponding to the time?
Best Regards,
Joy
