It seems that the default link prefix is “…/tx/” ,but the last “tx/” is not needed.
Its working from my end. Sometimes, block explorer unable to load transaction history can be also due to sync issue with block explorer.
Also, its only showing one tx in my end as provided on screenshot
Please go to settings > network > and check which which block explorer is added within zksync era network. You may also go to chainlist. org and add rpc for zksync era network and try again.
Thanks for your anwser . It indeed is my URI is wrong . Now it is correct now . Thanks again .
