Help the server is giving me problems

[plbp15]

The server is giving me a error when entering...Disconected by server you are connecting from a known proxy appeal at opticraft..... sorry for the off topic here but how can i enter the server?
I used the server almost everyday i don't know why it became like this....

There is nothing to be done on your part, just wait for Optical to assist you.
Thankyou for your patience
