I created a site that look like the poocoin site [https://poocoin.app/tokens/0x0901d1aca07aa728df1c45a29a90b86552909538](https://poocoin.app/tokens/0x0901d1aca07aa728df1c45a29a90b86552909538)

My site: [coinomic](https://polashmahmud.com/tranding-view?type=0x0901d1aca07aa728df1c45a29a90b86552909538)

but the problem is when I change the base currency address, sometimes it working fine, and sometimes it shows a CROS error.

Example (working):

Example (not working):

you can try.

The ones that don’t work on my site same addresses that work on poocoin site.

Can anyone tell me the reason for this?
