Dear Cloudhashmine Miners,

today, (Tuesday, the 27th), we conducted a technical update on our servers. We urge you to ensure that your rigs support the XNSUB extension.

The update only affected rigs not utilizing the extranonce subscribe extension (XNSUB) on the Equihash algorithm. 

Rigs that will not understand the message are effectively incompatible with us, and they will get a majority of their shares rejected with reject type 'Above Target'.

Fortunately, the majority of Equihash rigs are already equipped to handle XNSUB messages. However, we anticipate a higher rate of incompatibility with rigs operating on older firmware.

Addressing XNSUB Incompatibilities on Cloudhashmine

Your rig may not support XNSUB due to the following reasons:

1. The device supports XNSUB, but the user has not enabled it
2. The device lacks XNSUB support

1. Enabling XNSUB on your device for Cloudhashmine

To enable the extra nonce subscribe extension (XNSUB) on your ASIC or mining software, append the XNSUB extension at the end of your stratum line. 

2. The #xnsub string fails to enable XNSUB

If appending #xnsub does not activate XNSUB, it likely indicates that your device does not support this extension. In this scenario, we recommend updating your firmware to the latest version. Recent updates from manufacturers often include XNSUB support
