Language change to default after redirection

Dear Experts,

I am using nop 4.6 with two languages, en and ar, after redirection from bank payment  site nopcommerce shows default set language.
for example if customer use english using payment after redirection the nopcommerce changes to arabic site.
please help.

What payment method do you use?

Payment method is tahseel

Hi Rizwan, can you check customer on return time is same customer of is it guest customer?

Customer is same i check the customer id

Make sure your payment method uses the correct redirect URL, e.g. without a language prefix in it.

There is no any language parameter in redirect, but when i get the response i can see the laguage id is 1 which is arabic, but the current customer use english language
