Could it be that the clients have a (Windows?) firewall that blocks ping or other traffic that is from another subnet? I've seen that a few times, so it may be that the switch is properly routing, but the client is dropping the traffic in the firewall.
With your test that both clients can ping both IPs of the switch, you verified that routing on the client is setup properly.
With the command 'ip routing' in your config, and 'show ip route' showing both subnets, and 'show arp' for both VLANs you verified that the switch is configured and can reach both clients from a routing perspective. My guess is the client. If you can run Wireshark on the clients, you can verify if the traffic arrives on the client and if it responds to it or not.

Hi,
yes the Clients can ping the switches IP addresses.
For example:
Client a can ping 10.203.127.1 and 10.203.126.1
Client b can also ping both ip adresses

Can the clients reach the switch' IP address?
Can you share the output of the following switch commands: 'show ip', 'show ip route', 'show arp vlan 1' 'show arp vlan 126'?
