[SOLVED] No appropriate protocol (protocol is disabled or cipher suites are inappropriate)

no appropriate protocol (protocol is disabled or cipher suites are inappropriate)

We solved this ‘no appropriate protocol’ error by editing java.security file inside our JVM..

Three lines to be commented:
jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES, MD5withRSA, \
DH keySize lessThan 1024, EC keySize lessThan 224, 3DES_EDE_CBC, anon, NULL, \
include jdk.disabled.namedCurves

1.76 -> hi there i'm getting no appropriate protocol error when i'm starting my springboard application

8.72 -> i'm starting this application after a while but i didn't understand first why this error occurred

15.52 -> then after spending some time i finally got this thanks to stack overflow again so here i am going

22.16 -> to explain you how i resolved in my scenario okay so it's very simple so i'm if you see i'm using

31.52 -> java version 1.8.292 okay so before i think i have 1.8.181 okay so in between these times

42.32 -> if this subversion get updated so might be that might be the reason i thought then i googled and

48.4 -> i got a solution in the stack overflow so which is very simple so if you using your ubuntu then

54.24 -> you can directly go to your jre location okay in my case it is inside my user lib jvm and java 8 so

63.68 -> jre library security okay this is the path so jre library security until here it depends upon your

71.44 -> os and your machine okay where you have installed grt so if you see here inside

75.84 -> the security folder you are having java dot security so main computers here so what you

80.72 -> need to do is you need to open this okay and you will be getting something like this the whole

86.72 -> bunch of lines you have and what you need to do is you need to search for this particular line

92.72 -> okay i'll give you this particular line in this description so don't worry you can just

97.52 -> copy this and search in your java.security file okay so this is my file and i'm just searching

105.04 -> for this so i just copy this and control f control v yeah and here it is okay so if you see here java

113.52 -> dot security file this line is uncommented okay so quick hack is just comment this one

120.8 -> and that's it you will be able to start your server i need to provide a pseudo access to

125.76 -> update this so what i'm going to do is i am in the current path okay if you see pwd inside

132.32 -> java 8 open jdk security and if i list that folder i have this java security so what i'll do is

140.48 -> i'll just do sudo and i'm opening bim editor i'm going to open this java security file okay and it

149.52 -> asks for my password and i'm providing my password and here it is okay so if you see this line comes

156.24 -> java dot security file okay so so you can uh if you want to search in bim it's very simple you

163.04 -> can just put slash okay see slash oops okay and you need to type whatever the word you are going

170.56 -> to type so in my case i am going to type tls okay and just press enter after you enter the string

178.48 -> what you have to search then press n okay so you will get next next next occurrence so here it is

186.56 -> so to edit it i just need to press i i for insert c insert and my cursor is here i just come to this

195.52 -> line and i'm just commenting this commenting this line and commenting this line and escape and colon

204.08 -> wq to save the changes that's it and if i go to this particular project and if i start this

212.32 -> i'm hoping i really should start so let's wait yes i think it started yep so this is the issue so you

220.4 -> can also go and edit your java.security file if you are able to do and we go thank you bye
