Here is the link to the Attribute table size section of the S132 SoftDevice. You need to increase the NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE in sdk_config.h and then increase the RAM start address of the application by the same amount. Which IDE are you using, SES or KEIL?

The link in your answer is not working. Can you please provide a working link?
I'm using SDK v15.3.0 which has s132 6.1.1 to program an nRF521832.
Thanks

Yes, you have increase the IRAM1 start address corresponding to the increased size of the attribute table. This is described in this section in the S132 SoftDevice Specification.

I was able to solve the problem by

changing the BLE_GATTS_ATTR_TAB_SIZE_DEFAULT to 0x0700
Changing the IRAM1 start to 0x20003000 and size to 0xD000 in the Keil Target Options This probably result to extra available Ram for the Softdevice which was needed for the larger Gatts attribute Table
